Carlos Pe, of 1885 Guevarra St., Sta. Cruz was found dead by his common-law wife, Rebbeng Strebel, shortly after hearing successive shots from her own room. The couple sleeps in separate rooms in a three-bedroom house.
Nobody stays in the house aside from the couple but there was also no sign of forcible entry.
According to SPO2 Virgo Villareal, of the Western Police District (WPD) homicide unit, the incident happened about 3 a.m.
The motive of the killing also remains unknown as there appears to be nothing missing in the house except for Pes caliber .45 pistol. Pe sustained two gunshot wounds in the face and another two in the neck and left shoulder.
Police have yet to determine the type of firearm used in the killing.
Villareal said that although Strebel is not considered a suspect, she will have to undergo a paraffin test.
Strebel told investigators that her husband has a lot of enemies both in the neighborhood and in their business, but did not elaborate.
