At about 6:30 P.M. of May 30, 1968, while accused was downstairs. in the mezzanine of the store situated at the first floor of his house along Mabini Street, at Nasipit, Agusan del Norte, Raymundo Discipulo arrived thereat and after quite sometime asked the accused whether it was true that the loading of copra on the M/V Sweet Hope that day was given to Goring Gavero. Expressing his surprise as he could not believe then that it could happen because of his contract and good relation with the deceased, the accused was only able to answer: "Ha?" to Raymundo Discipulo's query (pp. 8-10, tsn, Aug. 26, 1969).
At about 7 o'clock that same evening, the accused left the said store, took a tricycle and went to the office of the Oceanic Enterprises and inquired for the deceased (pp. 287-288, tsn, April 15, 1969). Upon being informed by Leoncio Njai Acido, a copra sample man of the said Oceanic Enterprises, that the deceased was at the wharf, accused left and rode on the waiting tricycle bound for the town (pp. 287, 289, tsn, Id.).
At about 8:30 o'clock that same evening of May 30, 1968, while Carmelito Omboy was in his house fronting the plaza of the poblacion of Nasipit, Agusan del Norte, Dodong Ratilla, a nephew of the accused, arrived and told him (Carmelito Omboy) that the accused was requesting him to go to the latter's house (pp. 81, 82, tsn, Feb. 24, 1969). Soon thereafter, Carmelito Omboy went with Dodong Ratilla and proceeded to the accused's house located at a distance of only about 20 meters away and upon arrival thereat, accused who was then sitting by the door way beside a store (p. 82, tsn, Id.) stood up and commanded him ( Carmelito Omboy) to go to the wharf and to tell Joker (Atty. Jose Ong Oh, Jr., the deceased) to come to his (accused's) house because the latter wanted to talk to the former (pp. 83, 84, 86, tsn, Id.). Forthwith, Carmelito Omboy along with Dodong Ratilla took a tricycle and went to the wharf, a kilometer away, to look and fetch for the deceased (p. 87, tsn, Id.). Sometime after their arrival at the wharf, Carmelito Omboy was able to contact and convey the accused's message to the deceased who affirmatively said "Yes, I will be going there" and a little later rode in his jeep bound for the town followed by Carmelito Omboy in a tricycle (pp. 87-89, tsn, Id.).
Meanwhile, and that was between 8:30 and 9:00 o'clock that same evening of May 30, 1968, a wharf-bound cargo truck loaded with copra of the deceased and driven by Jose Mendrez developed engine trouble at the comer of Roxas and Mabini Streets in the poblacion of Nasipit, Agusan del Norte (pp. 233, 234, tsn, April 14, 1969) and stopped along Roxas Street at a point more or less seven (7) meters from the place where accused was sitting (p. 242, tsn, Id.). A short while after the said cargo truck stopped, and while its driver Jose Mendrez was still behind its wheel, the latter was approached by one named Charlito Canon who said to him "Nong, you are caged by Jesus Ruiz", referring to the accused. Jose Mendrez went down. the cargo truck and proceeded to where accused was sitting outside his store (p. 235, tsn, Id.). Accused gave Mendrez a glass containing Tanduay wine, a little of which the latter drank (p. 236, tsn, Id.). Accused inquired from Mendrez as to the whereabouts then of the deceased. Mendrez answered that he does not know because when he left the bodega, the deceased was not there (p. 237, tsn, Id.).
At this juncture then, and upon accused's instructions, Charlito Canon Nonoy Palabrica and another person unloaded from the stalled cargo truck three (3) sacks of copra which were then dropped along Roxas Street at the side of the said truck (p. 238, tsn, Id.). Thereafter, Charlito Canon stood at a corner fronting Roxas Street, while Nonoy Palabrica and the other person went behind the house of the accused (p. 239, tsn, Id.). Mendrez excused himself and went to the truck but upon reaching the same, Charlito Canon told him that accused was calling for him again (p. 239, tsn, Id.). So, he (Mendrez) went back to the accused who, while holding a glass of Tanduay on his left hand and with something protruding from his waist, told him not to go away, otherwise, he (accused) would shoot him (p. 240, tsn, Id.).
While Mendrez was thus being threatened by the accused, the deceased arrived in the vicinity riding in his jeep, but before the latter could alight therefrom, he was approached by Charlito Canon and soon thereafter, the deceased got down from his jeep and went towards the parked cargo truck and looked over at the sacks of copra lying on the street. Then he proceeded to the place where accused was (p. 241, tsn, April 14, 1969; p. 94, tsn, Feb. 24, 1969). Taking advantage of this opportunity, Mendrez left and went towards his parked cargo truck.
According to Carmelito Omboy who arrived at the vicinity almost at the same time that the deceased reached the place as the latter was followed by the former from the wharf, the devised greeted the accused "Jesse, Jesse" extending his arms to the accused who, however, slapped them and kicked the rattan stool and said, 'Sit down' to the deceased in a commanding manner (pp. 94, 95, tsn, Feb. 24, 1969); that the deceased picked up the rattan stool and placed it in front of the accused and sat on it (pp. 96, 97, tsn, Id.); that accused demanded, "Why did you load without asking permission?" (pp. 99, 100, tsn, Feb. 25, 1969); that the deceased answered "Jesse, easy, easy" (Id.); that accused then splashed a glass of wine on the face of the deceased and throw the glass to the concrete pavement (Id.); that the deceased stood up, wiped his face, removed his eyeglasses and wiped it with his T-shirt, wore his eyeglasses again and sat down anew, but accused with his right hand slapped him on the left cheek (pp. 99, 100, tsn, Feb. 25, 1969); that the deceased's face was turned to the right due to the impact of the slapping, only to be met by the shot from accused's black revolver (Exh. "F", p. 110, tsn, Id.) when the deceased turned his face to the front; that the accused got the revolver from his right waist and that only one shot was fired (pp. 101, 102, t.s.n., Id.); that the deceased jerked a little and fell to his left side, meanwhile the accused stood up still holding his revolver, raised it, turned its drum and tucked it on his right waist (p. 102, tsn, Id.); that thereafter, the accused turned to his right, and went upstairs of his house (p. 110, tsn, Id.) and threw his firearm (p. 45, tsn, Aug. 27, 1969); that after a while, accused came down from his house, passed by the body of the deceased, walked along Roxas Street and proceeded to the Municipal Building (pp. 111, 112, tsn, Feb. 25, 1969; p. 45, tsn, Aug. 27, 1969).
Sometime, thereafter, that same evening, the Chief of Police of Nasipit, Agusan del Norte, Teodoro Luneta, arrived at the scene of the shooting incident to investigate at the instance of Mrs. Lourdes Ruiz, wife of the accused (pp. 22, 24, tsn, Aug. 27, 1968). Chief Luneta saw near the house of the accused the body of the deceased (p. 28, tsn, Id.) whom he had known for a good number of years (p. 24, tsn, Id.). He did not see any firearms with or within the immediate vicinity of the victim (p. 58, tsn, Feb. 24, 1969). He left the place for a while to call some of his policemen to assist him, but upon his arrival at the municipal building, he saw the accused already there, so he ordered the station guard to keep watch on the person of the accused. As most of his policemen turned out to be on patrol, he went back to the scene of the crime, supervised the taking of the picture of the deceased on the spot, as well as the scene of the crime by photographer David, and the drawing of a sketch of the place (Exh. "B") by Corporal Jalop (p. 31, tsn, Aug. 27, 1968).
The body of the deceased was autopsied at the Raniel's Funeral Parlor at Butuan City by Dra. Lydia San Pedro, Municipal Health Officer of Nasipit, Agusan del Norte, at 2:00 o'clock in the morning of May 31, 1968 (pp. 140, 142-149, tsn, May 7, 1969), with the help of Dr. Teodoro Vesagas who did the actual incision (pp. 102, 149, tsn, May 7, 1969) and removed the slug which was lodged in the left medulla of the victim's brain (p. 116, tsn, Id.). The autopsy findings are reflected in the medical report (Exh. "T" and "T-3") submitted and testified to by Dra. Lydia San Pedro (p. 150, tsn, Id.) showing the following:
Ext.finding: Transicted tongue medially; commuted fracture left maxilla;

In the early morning of May 31, 1968, the recovered slug (Exh. "C") was handed by Dra. Lydia San Pedro to Chief of Police Luneta (pp- 36-39, tsn, Aug. 27, 1968; p. 152, tsn, May 7, 1969) who in turn gave it to his deputy, Police Lt. Amado Felias, with instructions to have it ballistically examined (tsn, pp. 36, 37, Aug. 27, 1968; p. 237, May 9, 1969), and to escort the accused to Camp Crame for the purpose of paraffin test, which mission he undertook together with Lt. Jose C. Edera of the Agusan PC Command that same morning of May 31, 1968 (tsn, pp. 30-34, May 5, 1969; pp- 239, 240, May 9, 1969).
According to Capt. Constantino Y. Leva Chief of the Ballistics Branch, PC Central Laboratory, Camp Crame (pp. 148, 149, tsn, April 18, 1969) and who examined ballistically the recovered slug (Exh. "C"), the said slug was fired from a Cal. .357 Magnum firearm (pp. 150-155, tsn, Id.).
The result of the paraffin test conducted on the accused also on May 31, 1968 by Lt. Col. Minardo B. Piñones, Chief of the Chemistry Branch, PC Central Laboratory, Camp Crame (pp. 326, 327, tsn, April 1, 1969), showed that the right hand of the accused was positive for the presence of nitrates, while his left hand was negative (Exh. "K"; pp. 336, 337, 388, 389, tsn, Id.).
On the same date, May 31, 1968, at Camp Crame, Quezon City, the accused executed an affidavit (Exh. "Z") stating therein that while he and the deceased were grappling for the possession of the deceased's revolver, somebody whom he did not see fired at the deceased. This affidavit, however, was not believed by Lt. Col. Pelayo Perez, CIS Deputy Executive Officer, when the said affidavit was presented to the latter on June 1, 1968 on account that it does not Identify who shot the deceased (pp. 174- 175, tsn, May 8, 1969), so that Lt. Col. Perez was constrained to, and did, interview, the accused (pp. 176, 179, tsn, Id.). After the interview, the accused, in the presence of Lt. Col. Perez, executed a second affidavit (Exh. "Z-1") giving a new version of the incident, in that it was the revolver of the deceased which killed the latter, and because of this new version, Lt. Col. Perez further interviewed the accused who finally admitted that he knew where the firearm was, and promised to surrender the same in Agusan if he (Perez) would go there. Forthwith, the accused was returned to Nasipit, Agusan, accompanied by Police Lt. Amado Felias and PC Lt. Edera (p. 240, tsn, May 9, 1969), while Lt. Col. Perez decided to follow them later together with CIS Agent Sofronio Sison (p. 182, tsn, May 8, 1969).
In the meantime, on June 2, 1968, P.C. Sgt. Manuel Leva a paraffin technician, lifted paraffin casts on the left cheek and both hands of the deceased (pp. 303-307, tsn, April 16, 1969). On June 6, 1968, these paraffin casts were turned over by Sgt. Leva to Lt. Col. Minardo B. Pinones, the Chief Chemist, who examined the same and the result (Exh. "L", p. 349, tsn, April 17, 1969) showed that the paraffin cast lifted from the left cheek of the deceased was positive for the presence of nitrates (pp. 346, 347, tsn, Id.), while the paraffin casts lifted from both hands of the deceased were negative (p. 348, tsn, Id.).
On June 4, 1968, Lt. Col. Perez arrived in Agusan and at the residence of the accused the latter surrendered to the former a Cal. .357 Magnum firearm with five have ammunitions and one spent shell (pp. 182-191, tsn, may 8, 1969; pp. 37-43, May 5, 1969), which firearm (Exh. "F") was found ballistically to be the firearm from which the recovered bullet or slug (Exh. "C") that killed Atty. Jose Ong Oh, Jr. (deceased) was fired (Exh. "P"; pp. 162-167, tsn, April 18, 1969).
On June 5, 1968, the next day after the accused surrendered the aforesaid firearm (Exh. "F"), he executed a third affidavit Exh. "Y") consisting of six (6) pages, at the Headquarters of the Agusan PC Provincial Command at Butuan City (pp. 193, 194, tsn, May 8, 1969), in which affidavit, accused, among others, admitted that the surrendered firearm (Exh. "F") is his own unlicensed revolver that killed the deceased, but that the killing was accidental as the forefinger of the deceased's left hand was inserted into the trigger guard of said revolver causing it to fire and hitting the deceased himself.
