Couple arrested in deadly collision in San Tan Valley

Investigators say a witness provided a license plate number that helped them track down a possible vehicle. They also discovered a Chevy Tahoe in the back of the Walmart.

Surveillance video showed that Boyd Palmer was driving that Chevy Tahoe, and in the passenger seat was 36-year-old Megan Palmer: the footage shows the Tahoe did not stop and slammed into the back of the van. Deputies believe the Palmers found a ride to get away from the crash scene.

Deputies tracked down the Palmers, who they say were intoxicated. Boyd Palmer was arrested for DUI, leaving the scene of a fatal crash, and manslaughter. Megan Palmer was arrested for hindering prosecution and possession of an open container.

Sheriff Paul Babeu stated, "A mother and father tragically lost their 17-year-old son because Boyd Palmer gotbehind the wheel of his Chevy Tahoe while impaired by alcohol and caused this fatal collision. I am proud of thegood work of our Deputies and Detective in tracking down these suspects as we will now seek justice. This is whywhen a deputy stops a driver on a traffic stop, we will never allow an impaired driver to park their car or get a ridehome. Impaired drivers will be arrested and charged every time. Our hearts go out to the Connely family for theirtragic loss."
