Suffolk police still are seeking information on the whereabouts of a 21-year-old man they have charged in the shooting death of another man on Cogic Square early Saturday morning.

Warrants are on file for Jeffrey O’Neil Jennings Jr., of the 400 block of St. James Avenue, following the death of Lloyd Randolph Green Sr.

Neighbors on Cogic Square said Tuesday they had not seen or heard the shooting. One man said Green was his cousin and was “a fun dude.” He would not give his name or talk further.

Police dispatchers received calls about shots fired a little after 1 a.m. Saturday. Police said the men were at a party, but the man who identified himself as Green’s cousin Tuesday said it wasn’t a party — just a typical weekend night.

Emergency responders arrived and found Green on the ground. A resident of the 300 block of South Broad Street, he was pronounced dead at the scene.

It was the third shooting death on Cogic Square in the last three years. Alissa Johnson, 25, died in a shooting there in July 2010, and 24-year-old Angelo Fleming Beale died on March 24 this year.

Police have filed arrest warrants for Jennings on charges of first-degree murder; shoot, stab, cut or wound with intent to maim or kill; shooting in commission of a felony; use or display of a firearm in commission of a felony; discharging a firearm in a public place with injury; and two counts of possession with intent to distribute cocaine.

Police have asked that anyone who knows Jennings’ whereabouts contact the lead investigators, Det. W. Shockley and Det. R. Cain, at 514-7939 or call Crime Line at 1-888-LOCK-U-UP. Callers to Crime Line do not have to give their names or appear in court. If information leads to an arrest, the caller could qualify for a reward of up to $1,000.
