DNA from flip-flops links man to Lancaster sex crime

June 2, 2012 12:00:00 AM PDT
Los Angeles County sheriff's deputies have arrested a man they suspect of groping a woman in her home by tracing DNA on the flip-flops he slipped off outside her apartment to avoid detection.

Christopher Prather, 20, of Lancaster, was charged Friday with burglary and sexual battery after entering the apartment of the 21-year-old woman Feb. 11.

Sgt. Mark Machanic says Prather watched the woman sleep. When she woke up, he whispered "excuse me," groped her and fled. The flip-flops were later discovered and sent to a lab for testing. Prather was arrested Tuesday, just hours after lab results were returned to Lancaster officials.

Prather was already on felony probation for robbery. He is being held on $170,000 bail.
