Pittsburgh police say a Brighton Heights man was in his early 40s when he began a years-long sexual relationship with a teenage girl that led to three pregnancies before she turned 18. 55-year-old Michael Anthony Wilson was charged Wednesday with involuntary deviate sexual intercourse, unlawful contact with a minor, statutory sexual assault and other offenses. A police affidavit says that the victim, who is now 26, told investigators that she had been in an “intimate relationship” with Wilson beginning around 2005 when she was just 13. The relationship continued over a period of about five years. According to the affidavit, Wilson got the victim pregnant when she was 14, 15 and 17 years old…and she had abortions when she was 14 and 17 and gave birth to a child from her pregnancy at age 15. The victim said told investigators that Wilson knew how old she was at the time and said that several of her family members confronted him.
