Maricopa County Sheriff's Office is investigating after a vehicle rollover in Laveen late Wednesday night.
The single-car crash occurred around 35th Avenue and Dobbins Road around 11 p.m. Three people were in the car at the time and were all taken to the hospital for treatment.
One person suffered life-threatening injuries, but was in critical, stable condition on Thursday morning. Two others had minor injuries after the crash.
MCSO says speed may have been a factor.
The road was re-opened after an overnight closure around 7:30 a.m.
