HAVERFORD TOWNSHIP, Pa. (CBS) — A man arrested for a deadly shooting in Haverford Township is back in custody in Delaware County and has been charged with first-degree murder.

Derrick Rollins, 24, was taken into custody last month in Decatur, Georgia, after being on the run following the shooting death of 29-year-old John Le. He was then extradited to Philadelphia.

Delaware County District Attorney Jack Whelan said during a press conference Wednesday that Rollins has been charged with first-degree murder, second-degree murder, robbery and other related charges.

Rollins is accused of shooting and killing Lee on July 29 near Haverford Road in Delaware County.

“We can’t even begin to imagine why he killed that innocent man who was just heading to his friend’s house,” said Whelan.

Whelan says the 24-year-old isn’t cooperating with the investigation.

“We have overwhelming circumstantial evidence,” said Whelan.

Rollins is also linked to another random attack in the Overbrook Park section of Philadelphia.

Police connected the two crimes using well publicized surveillance video and matching bullet casings.

“Obviously we don’t see this sort of thing in Haverford Township,” said Haverford Police Chief John Viola.  “It’s had a great impact on our community.  People are very concerned this happened in this area at all.”

Whelan said that Rollins fired 17 rounds at two neighbors in Overbrook Park and that they were able to identify Rollins as the man who shot at them and called police.

Whelan will be handling both the Haverford murder charges and the Philadelphia assault charges in Delaware County.  CBS3 asked if the lack of a clear motive for the crime could hurt the case against Rollins.  He said the case is still very strong.

“We have overwhelming circumstantial evidence,” Whelan said.

Rollins was denied bail. He has a preliminary hearing scheduled for Sept. 14.
