The Gila River Police Department released the identities of three people killed in a collision on State Route 347.
Juanna Molina, 24, Ray Molina, 33, and 18-year-old Dominic Dixon were pronounced dead at the scene of the accident after their pickup truck lost control on SR 347 on Nov. 29.
A fourth passenger was transported to a local hospital with non-life threatening injuries, according to a GRP press release.
The preliminary police investigation revealed the truck was traveling south on SR 347 about a mile north of Casa Blanca Road at 3:15 p.m. when the vehicle lost control and drove into the median.
“While in the median, the vehicle rolled once and rotated counterclockwise, and the vehicle continued traveling into the northbound lane of traffic with the rear of the vehicle leading,” according to the statement.
A northbound semi-truck was unable to avoid hitting the truck as a result.
Three agencies assisted the scene as traffic clogged the state route into the early morning hours.
Arizona Department of Public Safety and Arizona Department of Transportation assisted with road closures and GRP Traffic Unit assumed the investigation.
The statement said it is unclear whether impairment or distracted driving were contributors to the accident.
DPS previously reported the big rig driver received no injuries.
