PALERMO — Four men were killed Sunday in Maine’s deadliest crash of the year.

The accident occurred on Route 3 in Palermo, west of Augusta, when an SUV driven by Tyler Manduca, 18, of Bucksport lost control and skidded sideways into the path of the car driven by 64-year-old Dennis Sturges of Palermo.

Also killed were Manduca’s 21-year-old brother, Kyle Manduca of Bucksport, and Sturges’ 83-year-old father, Roy Lucier of Palermo.

State Police troopers said light snow was falling at the time of the crash, and Manduca was traveling too fast for conditions when he lost control of his vehicle, according to a prepared statement from Maine Department of Public Safety spokesman Steve McCausland.

Alcohol is not considered to be a factor, he said. Assisting troopers at the crash site were firefighters from the Palermo, Montville, Liberty and China fire departments.
