Six people were shot, three fatally, by gunmen in Bounty Hall, Trelawny on Friday morning.
The deceased have been identified as 24-year-old Daniel Williams, 26-year-old Tachae Black and 25-year-old Shanielia Clarke, all of Trelawny addresses.
Three other victims - all women - have been hospitalised in serious condition.
Investigators reported that shortly after 1 o'clock, Mr. Williams and the five women were returning from a party in Wakefield when they stopped at a yard in Bounty Hall to pick up a friend.
They were attacked by four men carrying rifles and handguns.
The gunmen opened fire on the vehicle, hitting the six individuals.
Superintendent Carlos Russell, Commanding Officer for the Trelawny Division, said the deadly shooting was a case of mistaken identity.
He said the incident is linked to gang activity in the area.
