WEST PALM BEACH — Jurors convicted a Broward County sheriff’s deputy of child sexual battery Thursday, moved by the testimony of the young woman he molested decades earlier.

Oshea, who asked to be identified by her first name only, cried while recounting the times that Verol Cowans violated her on the drives to Roosevelt Elementary in West Palm Beach, where she attended the third grade. She said the abuse escalated at home, where her mother’s then-boyfriend showed Oshea pornography and sexually assaulted her when the two were alone.
