A woman has been arrested on suspicion of negligent homicide in connection with a deadly three-vehicle crash Tuesday night on Interstate 10 in Tucson, authorities say.

About 9 p.m., Victoria Leticia Ralston, 40, stopped the pickup truck she was driving west on the interstate near the Valencia Road exit, the state Department of Public Safety said in a news release.

Ralston was booked into the Pima County jail, the state DPS said.

A vehicle driven by Rigo Tong, 26, struck the back of the pickup truck.

Then, a tractor-trailer smashed into both vehicles, according to a news release.

Tong was pronounced dead on the crash scene, the release said.

Tong had just celebrated five years of employment at Maid Rite Feeds feed store, the company said in a social media post.

“Rigo was such a hard and dedicated worker. So polite and caring,” his employer wrote. “His family is in need all of all the prayers and help during this difficult time. Please hug your loved ones extra tight and tell them how much they mean to you. You will be extremely missed Rigo.”
