Police have released the identities of two people killed yesterday in an accident on I-95 in Wells.

Public Safety spokesman Steve McCausland says the accident happened around 2:30 Friday afternoon as traffic was slowing down because of an unrelated second crash at mile 24. In that accident, a man was critically injured when his vehicle struck guardrails and he was thrown out of the car. Police haven't released that driver's name.

Killed in the two-vehicle crash were 57-year-old Earl Gray of Waterboro and 5-year-old Wyatt Frost of Lyman. Gray was a volunteer driver with York County Community Action and had provided transportation to the boy for a couple of years. The two died when a box truck struck the rear of Gray's car and then landed on top of it. The driver of the box truck was 56-year-old John Kamau of Lowell, Massachusetts. Kamau was delivering mail from NH to Portland. The impact drove Gray's car into the rear of a tractor trailer that was ahead of it.

Troopers say the accident report will be forwarded to the York County District Attorney's Office to determine whether charges will filed.
