ST. AUGUSTINE, Fla. -

A St. Johns County judge on Friday sentenced a 52-year-old man who pleaded no contest to DUI manslaughter in the death of 18-year-old Shae Burchfield to 5 years in prison plus 10 years probation.

Prosecutors say Frederick Andrews had Xanax, cocaine and methadone in his system while driving a pickup truck that struck Burchfield on a dirt bike on July 8, 2010.

Shae Burchfield The Florida Highway Patrol said witnesses saw Andrews driving erratically before hitting Burchfield's dirt bike head on.

Andrews, of St. Augustine, was given credit for 588 days spent in jail awaiting trial, but faces lifetime suspension of his driver's license.

Andrews also received 5 years on a conviction for bringing drugs into the St. Johns County Jail -- to be served concurrently with the manslaughter sentence -- with 426 days credited for time already served.

"I can't say we're happy with (the sentence), but I can say we're satisfied," said Carl Burchfield, the victim's grandfather. "This is over and we can move on with our lives, and maybe Mr. Andrews' family can move on with their lives, too."

In the years since her death, the city of St. Augustine has named a park in Shae Burchfield's honor.
