Kyle Brian Gowen, 22, and Steven Shaun Gowen, 21, both of Eastern Passage, N.S., were arrested Saturday and will appear in Truro provincial court Tuesday to face first-degree murder charges.

They are accused of killing Dillon Blair Jewett, who was found shot to death near East Uniacke, in Hants County, on Oct. 3.

Amanda Allison Greene of Cow Bay, N.S., already appeared in court Oct. 25 charged with first-degree murder in Jewett's slaying.

RCMP Sgt. Brigdit Leger would not confirm that the two men arrested Saturday are related, but said the three accused know each other.

Kyle Gowen was arrested at the Irving gas station in Eastern Passage where he worked. Greene was also arrested there earlier this month.

Steven Gowen was arrested in his nearby home.

Greene is an 18-year-old Dalhousie University student and Jewett's former girlfriend.

A group of people riding dirt bikes and all-terrain vehicles north of Halifax discovered Jewett's body on a path in a quarry.

The RCMP has said Jewett was shot to death and was identified through his fingerprints.

They have not said when they believe he was killed, how long his body was in the quarry or what led them to Greene.

Greene is to appear in court again Nov. 25.
