A third suspect is behind bars on a murder complaint, accused of killing a Harrah man back in August.

Investigators booked 19-year-old Aaron Wilson into jail Monday.

He's behind bars without bond.

"It broke my heart, I was in tears, shaking," said one neighbor.

Weeks after beloved Harrah resident Stephen Courtemanche, 64, was gunned down in his home, with no arrests his family pleaded for answers.

"We stayed out there for hours that evening and just waiting for somebody to tell us something," said sister-in-law Rita Griffin.

Soon after, investigators arrested Cameron Long, 15, and Robert Stockton Jr., 17.

Monday, Wilson was also arrested.

According to court documents, while the three teens could not agree on who pulled the trigger, killing Courtemanche, they admitted to going to his home in order to steal guns.

Records showed Wilson kicked open the front door, the three entered, then shot and killed their sleeping victim.

"I don't know if I can wrap my brain around it," said one neighbor.

"Steven Courtemanche was the best guy in the world, he would do anything for anybody," said Griffin.

In another case-- Stockton Jr. is accused of killing his stepfather, Anthony Cannon, between July and August.
