A news conference is expected on the deadly home invasion that happened in Harrah back in August. It's expected at the Oklahoma County Sheriff's Office at 10:30 Thursday morning.
The Sheriff is expected to deliver updates on the 3rd suspect just arrested on Monday.
19-year-old Aaron Wilson is in the Oklahoma County detention center right now without bond.
He is the third person arrested on a murder complaint, accused of killing 64-year-old Stephen Courtemanche back in August.
15-year-old Cameron Long, and 17-year-old Robert Stockton Jr. have also been arrested in the case.
According to Court documents, the three teens arrested could not agree who pulled the trigger allegedly killing Courtemanche but did admit into going into his home to steal guns.
Records continue to show Wilson kicked open the door, the three teens entered, then allegedly shot killed the 64-year-old victim.
For weeks following the murder, Courtemanche's family pleaded for answers, before the arrests were made.
"We stayed out there for hours that evening and just waiting for somebody to tell us something," said sister-in-law Rita Griffin.
Stockton Jr. is also accused of killing his stepfather earlier this year. The Sheriff's office says he started a fire to cover it up.
