The man killed last weekend in a Gambell Street motorcycle crash was an Army soldier, military officials confirmed Monday.

Staff Sgt. James Alcorn, 35, was a field artilleryman assigned to Joint Base Elmendorf-Richardson's 4th Brigade Combat Team (Airborne), 25th Infantry Division according to U.S. Army Alaska spokesman John Pennell.

Alcorn, who joined the Army in 2006, served at Fort Benning, Fort Knox and Fort Bragg in the southern U.S. before being assigned to JBER in July 2016. He had served two combat tours in Afghanistan, as well as one in Iraq.

"Staff Sgt. Alcorn was an amazing paratrooper, leader, and non-commissioned officer," said Lt. Col. Tobias Bennett, the commander of Alcorn's battalion. "He was well-known throughout the battalion for his technical and tactical competence, his upbeat personality, and his ability to motivate and care for his paratroopers. He will truly be missed by all who knew him."

Police had responded at about 2:35 p.m. Saturday to the crash, which closed Gambell and Ingra streets between East 15th Avenue and Fireweed Lane.

APD spokeswoman Kendra Doshier said in an email that no other vehicles were involved in the wreck. Alcorn was pronounced dead at the scene.

"The preliminary investigation found that [Alcorn] was traveling at a high rate of speed and lost control of his vehicle," Doshier wrote. "Speed is believed to be the only factor at this point."

An APD statement said the two closed streets reopened at about 6:30 p.m. Saturday.
