A deadly exchange between brothers

Two Philadelphia brothers, both with lengthy criminal records, allegedly engaged in a deadly argument Monday evening.

Police responded to reports of a person with a gun at 6:35 p.m. Monday, on the 5100 block of Kershaw St. in Parkside. On arrival, police found Jacquell Roundtree, 31, on his front porch with gunshot wounds to his back and side. He was transported to Penn Presbyterian Medical Center where he died shortly after 9 p.m.

Police said Wednesday they were seeking a suspect, Dominic Roundtree, 29.

Both brothers were in the news within months of each other in 2005. In January, Dominic Roundtree was arrested by Cherry Hill police after allegedly attempting to cash a suspected forged check. He was carrying a loaded handgun and 17 grams of crack cocaine when he was arrested, according to police at the time. He was 18.

Jacquell Roundtree scuffled with police at the Criminal Justice Center in Philadelphia in March that year after he was sentenced to four to 23 months in jail for violating the terms of his probation. He attempted to run out of the courtroom when the verdict was announced but was captured by police, according to reports at the time. Then, within an hour, police found him hanging from a vent inside his basement cell by the drawstring of his sweat pants in what was described as an attempted suicide.

Two other separate shootings in the city Monday left one man dead and another wounded.

Sadiqq Gant, 21, of the 600 block of West Wingohocking St. was shot to death in the Ogontz neighborhood shortly after 4 p.m. Monday. He was transported to Albert Einstein Medical Center where he was pronounced dead. No arrests had been made as of Tuesday morning, police said.

Another shooting Monday evening left a victim in critical but stable condition. The man, 20, suffered gunshots to his left shoulder shortly before 9 p.m. on the 6600 block of Haverford Ave., police said. Police were seeking two suspects on Tuesday.

Correction: An earlier version of the story, citing police, incorrectly reported that the suspect was in custody in the Kershaw Street slaying.
