A police officer's son was one of three people shot dead in Santa Cruz yesterday.
A fourth man is currently warded at the hospital nursing gunshot wounds.
Dead are 19-year-old Francois Hall, whose father is a police officer, Ian Garcia, 45, and a third man identified by the alias "Darko".
Jamal Bonne remained warded at the Eric Williams Medical Sciences Complex (EWMSC) in a serious condition up to late yesterday.
According to police reports, around 10.40 am on Kingston Avenue in La Canoa, Santa Cruz, two warring gangs in the area opened fire on each other.
Hall and Darko died on the spot, while Garcia and Bonne were taken to the hospital.
Garcia eventually died while undergoing treatment.
Hall, an aspiring footballer, was said to be willing to assist anyone in the community. His killing was described as senseless.
The triple murder and the shooting death of another man in Cumuto accounted for four killings yesterday morning.
Hours before the La Canoa shooting, a 31-year-old man was killed in a separate incident in Cumuto.
According to reports, around 4 am David King was at his family's Cumuto home when four intruders entered.
King was in his backyard when he was approached by the four men armed with guns and cutlass. King was chopped.
His neighbour ran across to assist him after hearing the commotion and also received chop wounds.
King died on the scene while his neighbour was taken to the hospital to receive medical treatment.
The four intruders remain at large.
Homicide detectives are investigating the killing and a motive is still to be determined.
