Six young men are facing murder charges in the deaths of Jesse James and Emmanuel Amoah in September.

Police said the charges come after a long investigation involving 60 officers. Police would not say whether gangs or drugs were involved in the murders though officers of the Edmonton Police Service's drug and gang unit were part of the investigation.

James, 23, was shot to death Sept. 4 in the parking lot of a southside condo near Saddleback Road. At the time police said James was known to them and did not believe the shooting to be a random incident.

Amoah’s remains were found Sept. 14 near Ellerslie Road and 17th Street. He last seen alive Sept. 1.

Amoah, 19, was a student at City Centre High School.

Police announced the arrests in the two cases Monday.

Mahamed Abdulle, 19, and an 18-year-old, who was a minor at the time of the slayings, each face two counts of second-degree murder and offering an indignity to a dead body.

Jason Kadeem Williams, 19, and Christopher Macoon-Evans, 21,  face second-degree murder charges in James's death.

Two other teens — aged 18 and 16 — are charged with second-degree murder and offering an indignity to a dead body in Amaoah’s death.
