The driver in a wrong-way crash early Sunday on Interstate 19 was a bartender at American Legion Madera Post 131 and worked at a restaurant in Green Valley.
Post 13 Commander Thom Johnson wouldn't release details about Tambra Hoskins, 52, who officials said drove her gray Camaro southbound in the northbound lanes, striking a Nissan Sentra and killing three people about 12:45 a.m.
Hoskins also died in the crash.
“We fully expect to be interviewed by county officials so I don't want to comment until I talk to them first,” Johnson said Monday.
Ronnie Black, manager at San Ignacio Golf Course, said Hoskins was a server at the Coyote Grill.
DPS officials released the names of all the victims Monday.
The crash killed the driver of the Sentra, Edith A. Munoz, 41, and her sons, Mario A. Gradillas, 24, and Saul E. Gradillas, 19, all of Tucson. A 14-year-old boy was thrown from Munoz's vehicle and taken to a Tucson hospital in critical condition.
The crash occurred on northbound I-19 between Continental and Canoa roads in Green Valley. Hoskins was alone in her vehicle.
DPS said, "Impairment will be determined by the medical examiner and the investigation is ongoing."
