Daniel Bartelt, 19, was charged with homicide on July 31st in connection with the death of Wisconsin teen actress Jessie Blodgett.
Blodgett was found dead in her bedroom July 15, 2013 following a cast party, CBS affiliate WDJT reports.
Investigators discovered ligature marks on the teen's neck, who had performed in a production of "Fiddler on the Roof" hours before her death, according to the report.
Documents indicate Blodgett's mother placed clothing in her daughter's bedroom around 8 a.m. When Blodgett's mother returned home from work shortly after noon, she discovered her daughter dead in her bed and called 911.
Police don't have a motive yet, but say Bartelt and Blodgett had dated in high school and had been spending time together.
Bartelt was arrested July 17 after he admitted to a separate attack of a woman in a park on July 12. He faces three felony counts in connection with that attack, in which the woman says she was cut with a knife.
