PEORIA, AZ — Police say a 19-year-old man went on a violent shooting spree across the West Valley on Thursday that lasted just 90 minutes, but left one person dead and a dozen others injured.

Ashin Tricarico was taken into custody just after 12:30 p.m. Thursday, after drive-by incidents in Surprise, Peoria, and Glendale.

According to police reports released Friday afternoon, Tricarico's first offense actually happened Wednesday evening outside a Peoria Circle K before his extended series of drive-by shootings on Thursday morning.

Shooting incident #1

At 6:15 p.m. on Wednesday, June 16 (the day before the string of shootings in the West Valley), a man called 911 from the parking lot of Circle K, near Olive and 95th avenues, and said a man in a white Volkswagen pointed a gun at him.

The victim told police that he was talking to his wife and laughing and thinks the suspect may have thought he was laughing at him.

The suspect then chambered a bullet and pointed a gun at the victim.

Both the victim and suspect left Circle K in separate vehicles and were driving in the same direction along Olive Avenue.

Near 99th and Olive avenues, the suspect made a U-Turn and then pointed an assault rifle outside his driver's side window.

The victim, fearing he was going to get shot, ducked and thought he heard glass break. The victim was on the phone with police dispatch, who also heard the sound of a gunshot, police said.

Documents say that the victim did not think his vehicle was struck and no projectile strikes were found on his vehicle. The victim was unharmed.

Ammunition is purchased

On June 17 at 11 a.m., the suspect left his house with an AR-15 rifle and went to an unknown car wash on Bell Road.

The suspect told police that an unknown man followed him into the car wash and pointed a gun at him.

The suspect told police that at this moment he realized he did not have ammunition with him.

At some point, the suspect went to Cabela’s and bought four boxes of ammunition for his rifle.
