David Leroy French, 21, was arrested in connection with a mass shooting in downtown Tucson Sunday that left nine people critically injured, court records say.

At the time of the incident French was serving a four-year probation term for a 2024 aggravated assault with a deadly weapon, court records show.

At about 2 a.m. Sunday, after a verbal argument, French allegedly opened fire into a crowd near East Congress and North Sixth Avenue, striking nine people, an interim complaint says.

Nearby Tucson police officers heard the shots and saw a man running away from the scene, police said in a news release.

Through reviewing surveillance footage, investigators confirmed French was the shooter, the complaint says.

French was arrested on suspicion of nine counts of aggravated assault with a firearm, nine counts of aggravated assault, and discharging a firearm at a structure, the complaint says.

During the 2024 incident, French and some other people were hanging out at a car wash in the early morning of Oct. 6, 2024, when an employee asked them to leave, court records say.

French, who had pulled out a rifle, and two others confronted the employee. The employee ran away from the group towards the median of a nearby road, court records say.

Surveillance footage from the incident shows French pointing the rifle at the employee and firing in his general direction, court records say.
