(NEXSTAR) — A Georgia man was arrested after three people were killed at a Georgia shooting range on April 8.

The Georgia Bureau of Investigation (GBI) announced Friday it arrested 21-year-old Jacob Christian Muse, of College Park. Muse was booked into the Coweta County Jail and is charged with three counts of malice murder.

Police in Grantville responded to the Lock Stock & Barrel Shooting Range at about 8 p.m., where they found the bodies of the range’s owner, his wife and their grandson. The range had also been robbed of “approximately 40 weapons” and a digital camera, the Grantville Police Department wrote on Facebook.

Due to the nature of the crime and the theft of the weapons, the Georgia Bureau of Investigation and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) were called in to work the case. The sheriff’s department in Coweta County is also assisting, Grantville Police confirmed.

Authorities are now asking anyone who may have seen a suspicious vehicle at the shooting range on Friday evening to contact police.

“Please share, maybe someone will remember seeing something to assist with the investigation,” the department wrote on Facebook.
