PHILADELPHIA—Police have charged a gambling figure in a brazen daytime shooting that could be the first mob slaying in the city in nearly a decade.

Anthony Nicodemo was charged Thursday with killing Gino DiPietro in broad daylight near the victim's home.

The shooting occurred just hours after prosecutors Wednesday wrapped up their two-month case in the racketeering trial of Joseph "Uncle Joe" Ligambi, who's accused of being a mob boss, and six others.

DiPietro's name has come up in wiretaps played in court, and one of the Ligambi trial prosecutors handled his 2008 federal drug case.

Defense lawyer Christopher Warren, who represents Ligambi co-defendant Joseph "Scoops" Licata, said the jury might have heard about the slaying, which could affect his client's case.

"Three hours after the government closes, somebody is murdered on a bright sunny afternoon at 3 o'clock?" Warren said. "There's no way in the world the jury doesn't hear about this."

U.S. District Judge Eduardo Robreno on Thursday said he would ask jurors if they've heard anything about the slaying. The jury returns Tuesday, when the defense is set to begin its portion of the case.

The defense has repeatedly argued that the gambling and loansharking case is devoid of the kind of violence that marked mob trials in previous eras in Philadelphia. Even the indictment suggests the 73-year-old Ligambi has run the mob for the past decade with a focus on making money, not ordering murders.

Nicodemo has been held for questioning since shortly after DiPietro's death. He quickly emerged as a suspect after police traced the vehicle and license plate spotted at the scene to his nearby home.

But police on Thursday weren't ready to make the mob link.

"We are not treating it as mob-related or not. This is one man who killed another man," police spokeswoman Tanya Little said.

Nicodemo was charged with murder and awaits a bail hearing. He was in custody and couldn't be reached for comment, and it was unclear if he had a lawyer. A woman who answered the telephone at his home said the family had no comment.

Nicodemo remains on probation in the 2009 gambling case after pleading guilty to a low-level role in an illegal betting ring that operated out of the poker room of the Borgata Hotel Casino & Spa in Atlantic City, N.J.

The state judge in that case called the ring "highly organized" but rejected claims by investigators that it was tied to the mob.

DiPietro, 50, had pleaded guilty in a 2008 federal drug case handled by Assistant U.S. Attorney David Troyer, one of the Ligambi prosecutors. He was charged with selling cocaine to two lower-level dealers.

Details of his plea agreement and sentence are not listed on the docket. He had also been convicted in a 1997 federal drug case that netted him a 97-month sentence, court files show.
