A prostitute who was with former Villanova basketball star Howard Porter on the night he was beaten aided and abetted his killing, according to a criminal complaint released Thursday.

Porter, 58, died May 26, a week after he was found unconscious in a Minneapolis alley.

Tonya Evette Johnson, 33, is charged with second-degree murder for her role in Porter's death. She told authorities that she was walking near her St. Paul apartment when she approached Porter for a "date." Johnson said she brought Porter to her apartment to exchange sex for money and crack cocaine when four masked men rushed in and beat him, according to the complaint.
