A Philadelphia Common Pleas Court jury this afternoon convicted a retired, 23-year Philadelphia police officer guilty of multiple sex charges for carrying on a sexual relationship with a woman that began when she was 12 and continued into adulthood.

The jury returned about 2:30 p.m. after finding Tyrone Wiggins, 51, guilty of four sexual assault charges including corrupting the morals of a minor. The jury, however, acquitted Wiggins of rape.

The victim, now 25 and herself a police officer, broke into deep sobs after the verdict.

Wiggins, an 8th-degree black belt who began the sexual relationship when the woman was a student in his Olney karate school, showed no apparent emotion at the verdict.

Judge Sandy L.V. Byrd ordered Wiggins taken immediately into custody pending a sentencing on March 25.
