A judge in McKinney on Tuesday accepted the plea agreement with ex-Sulphur Springs police Chief Donald "Donnie" Gene Lewis. Investigators accused Lewis of having sexual relations with a girl between 2001 and 2004.
A Collin County grand jury last year indicted Lewis on three counts of aggravated sexual assault of a child, eight counts of indecency with a child/sexual contact and five counts of sexual assault of a child.
He pleaded guilty to 10 counts of indecency with a child.
Lewis was a Sulphur Springs officer for more than 25 years before retiring in 2001. He later moved to Dallas.
Sulphur Springs is 75 miles northeast of Dallas.
