PHILADELPHIA — Federal marshals Tuesday arrested a man wanted for an attempted homicide three weeks ago at a busy Butler intersection.

Hassan “Money” Lamar Brack, 26, was nabbed about noon at a car stereo and alarm business in Philadelphia.

The U.S. Marshals Fugitive Task Force was looking for Brack, who had been wanted and was considered armed and dangerous since Aug. 19, when he allegedly shot a man at East Cunningham and South McKean streets in Butler.

Butler County sheriff’s deputies traveled to Philadelphia today to pick up the suspect and return him to Butler, according to Sheriff Mike Slupe.

“He’ll be back here by day’s end,” Slupe said this morning.

Later, Brack will be arraigned on charges of attempted homicide, aggravated assault, aggravated assault with a deadly weapon, illegal possession of a firearm and reckless endangerment.

Capt. David Dalcamo said Butler police plan to ask the arraigning district judge for a “significant bond” to hold Brack in the Butler County Prison.

The defendant has already proven to be a flight risk, Dalcamo said.

For days after the shooting, city police searched for but were unable to find Brack. Police knew Brack had previously lived in Butler’s Island neighborhood but they had no fixed address for him.

Police immediately speculated that he could have fled to his native Philadelphia.

Details of his arrest Tuesday were not known. A telephone call to the Marshal’s Service Eastern District of Pennsylvania office in Philadelphia was not returned this morning.

Butler police on Aug. 20 obtained an arrest warrant for Brack, a convicted drug dealer and robber.

Investigators allege the defendant got out of a sport utility vehicle, came up to another vehicle and shot its passenger, 25-year-old Brannon Irvin of Butler, in the chest.

The shooting occurred about 7:30 p.m. amid other traffic and witnesses.

Irvin underwent at least two surgeries at Allegheny General Hospital in Pittsburgh for his injuries. He later was released and is still recovering, authorities said.
