Suspect arrested in 2012 homicide at Carmichael residence

A man sought in connection with a 2012 homicide in Carmichael has been arrested after sheriff’s deputies located him during a vehicle stop.

Shamar Armstrong, 24, of North Highlands was stopped about 11 p.m. Tuesday near Roseville Road and Longview Drive and arrested without incident on a warrant, according to a Sacramento County Sheriff’s Department news release. He is accused of murder in the fatal shooting of 24-year-old Andrew Coy during a marijuana deal.

Deputies were called to the 5700 block of Haskell Avenue on Aug. 20, 2012, regarding a man who had been assaulted. When they arrived, they found Coy inside a residence with a gunshot wound to his upper body. Medical personnel pronounced Coy dead at the scene.

The shooting reportedly occurred during a marijuana deal that had been set up between Coy and three people, including Armstrong. Once Armstrong and his companions were inside the residence, they pulled guns on Coy and his friends and demanded money, according to the news release. One of the people shot Coy and also fired at one of Coy’s friends, but missed. The shooter and his companions then left in a dark-colored four-door sedan.

Detectives determined that Armstrong was at the scene and was one of the three people involved in Coy’s shooting death, the news release said. The Sacramento County District Attorney’s Office reviewed the case and submitted a warrant for Armstrong’s arrest.

Armstrong was booked into Sacramento County jail on suspicion of murder and attempted murder and currently is ineligible for bail. He is to be arraigned Friday in Sacramento Superior Court.

Detectives are still working to identify the other two people involved in the shooting. They were described as black men in their 20s. Armstrong’s booking photo has not been released because of the ongoing investigation, according to the Sheriff’s Department.

Anyone with information pertaining to the case is asked to call the Sheriff’s Department at 916-874-5115 or Sacramento Valley Crime Stoppers at 916-443-4357. Tip information also may be left anonymously on the Sheriff’s Department’s website,, or by calling 916-874-8477.
