NEW KENSINGTON, Pa. – The man suspected of shooting and killing a Pennsylvania police officer was captured Tuesday, officials said, ending a three-day manhunt, reported Fox News.

Rahmael Sal Holt, 29, was taken into custody Tuesday morning, the Pennsylvania State Police said in a tweet. However, it wasn’t immediately clear where and how he was captured as it lacked details. A press conference is scheduled for later today.

Authorities filed charges of first-degree murder and murder of a police officer against Holt on Saturday.

Holt is accused of killing New Kensington police officer Brian Shaw Friday night about 18 miles northeast of Pittsburgh. Shaw, 25, was conducting a traffic stop when he was shot in the chest. Consequently, he was rushed to the hospital where he later died.

Investigators said they know what prompted the initial traffic stop, but they’ve yet to reveal the information publicly. A reward for information leading to Holt’s arrest topped $55,000 on Monday.

The FBI, Marshals, Allegheny County Police and the Pittsburgh SWAT team surrounded a home in the 5000 block of Ladora Way. They had been following Holt throughout the night as he moved from Duquesne to Homewood and eventually to the home in Hazelwood, reported CBS Pittsburgh.

Three people were arrested for hindering Holt’s apprehension, including his mother, the station says. Four other people were arrested on outstanding warrants.

On Sunday, police arrested Tavon Jamere Harper, who they allege fled the traffic stop after Holt bolted from the SUV.

They tracked down Harper and found him Saturday with $2,500 cash and bags of suspected heroin, according to a criminal complaint.

The next day, detectives filed drug and fleeing charges against Harper. He doesn’t face charges in connection with Shaw’s death.

Shaw’s friends remembered him as a happy, helpful man who loved being a police officer, reported

“Ever since he was 17 or 18, that was all he talked about,” said Shaw’s friend, Allie Wilhelm. “He was like, ‘It’s my calling.’”

“I ran into him about six months ago, he was in uniform and he looked great. He looked happy, so happy,” Wilhelm said.

“He was a great family man and always thought about his community, and always wanted to help anyone he could,” said classmate David Fleck.

Ciara Herbst, Shaw’s friend and former coworker, said Shaw’s happiness was infectious.

“He was the most genuine guy,” she said. “He honestly cared about everyone and wasn’t leaving somewhere unless everyone had a smile on his face.”

Finally, Shaw served as a part-time officer in three other towns before joining the New Kensington force full time in June. As a result, he will be missed in many places.
