According to a lieutenant at the scene, Phoenix police responded to two people with gunshot wounds just before 2 a.m. near 27th Avenue and McDowell Road .

Police found that the man and woman were initially shot at a home near 51st Avenue and McDowell Road . They attempted to drive themselves to the hospital but ended up stopping near 29th Avenue and McDowell Road to call 911.

The suspect fled the scene south on I-10, where Arizona Department of Public Safety troopers and police officers followed him to the Marana area, which is just north of Tucson.
