READING, Pa. -

A Reading man being sought in the shooting deaths of two people in Idaho's capital city is now in custody.

Reading police and a pair of detectives from Boise arrested John Douglas without incident as he was walking near his home in the 400 South Seventh Street on Monday morning, officials said.

Douglas, 44, is facing a pair of murder charges in the killings of two men and an attempted murder charge in the wounding of a woman inside an apartment in Boise on May 8, police said.

"Boise police appreciate the cooperation of the Reading Police Department in assisting with a case that has been a priority for Boise officers," said Sgt. Mark Barnett, Boise Police Department.

Another suspect, Samari Winn, is already in custody and facing trial on two counts of aiding and abetting murder and one count of aiding and abetting attempted murder. Authorities have said Winn was not the person who pulled the trigger.

Winn’s attorney has said in court that the victims, identified by police as Travontae Calloway, 27, and Elliot Bailey, 28, both of Boise, stole 30 pounds of marijuana before their deaths.

The injured woman was reportedly Calloway's girlfriend, who was shot in the arm.

Douglas has not told police why he was in Boise at the time of the killings. He will be held in the Berks County Jail until his extradition to Idaho.
