The Texas Department of Public Safety (DPS) has released the identity of a truck driver who was fatally shot by police last week after reportedly shooting his co-driver multiple times.

The incident occurred on Friday, September 23, near Chillicothe, Texas.

According to Texas DPS, Texas-based truck driver Darian Patrick Fisher, 41, was fatally shot by police after shooting his co-driver, Federico Alvarenga, Jr., 31.

Around 7 a.m. on Friday, Alvarenga called 911 and reported that his co-driver Fisher had shot him.

The Hardeman County Sheriff’s Office (HCSO) was able to verify that the caller was in a moving vehicle on southbound U.S. 287 east of Quanah, Texas.

HCSO located the semi truck still traveling south on U.S. 287 and a 10 mile police pursuit ensued.

Fisher stopped and exited the truck from the passenger side door, firing at law enforcement officers multiple times with a handgun.

Police returned fire, striking Fisher. Fisher died at the scene.

Texas DPS says that they still do not know why Fisher shot Alvarenga.

Texas DPS also gave an update on Alvarenga’s condition. Alvarenga underwent surgery for multiple gunshot wounds and is listed in stable condition, but may be paralyzed due to spinal cord damage.

The Texas Rangers are investigating the shootings.
