Amarillo police are investigating what is believe to be an accidental discharge of a firearm at the Walmart on Canyon Drive on Tuesday.

According to press release, officers were called at 2:37 a.m. to the Walmart at 4215 Canyon Dr. on reports of an accidental shooting.

Officers determined that an adult white male was walking down an aisle in the store when his gun went off. He was injured in the abdomen and right leg and the man fell to the floor, police said.

Initial reports stated the man was alone, but "additional review of the case indicates there was a second person in or around the person who shot himself," said Sgt. Brent Barbee of the Amarillo police department.

Additional details are unclear as to whether the gun was in the man's pocket or waistband, police said.

The man left the store before an ambulance arrived and told officers that a friend drove him to the hospital, according to a press release from APD.

The man told officers that he had put the handgun in a nearby trash can and a .357 caliber revolver was later recovered from a trash can at the store.

The incident has been classified as an unlawful carry of a firearm violation, since the man was not found to have a Texas license to carry a firearm.

Sgt. Barbee clarified that the man could potentially have a handgun permit from another state that Texas honors in a reciprocity agreement.

This particular Walmart has already seen several tense situations in the past two months, including a bomb threat on July 19 and a hostage situation on June 14 that resulted in the death of Mohammad Moghaddam, 54.
