LINCOLN, Maine (WABI) - A convicted child sex offender in Lincoln has admitted to having child pornography.

36-year-old Derrick Coffin changed his plea to guilty Monday in federal court in Bangor.

He pleaded not guilty last year.

Coffin is a registered sex offender for life.

In 2006, he admitted to breaking into a home in Raymond and attacking a 10-year-old boy.
