PHILADELPHIA — The ex-boyfriend of 17-year-old Ashley Burg www.adultfyi.com/read.aspx?ID=11177 spoke out on TV Tuesday for the first time about her mysterious death.

Police believe she died of a drug overdose, but they still don’t know where she died.

Her body was dumped in a wooded area in the Crestmont Farms section of Philadelphia on July 31.

Police said that Burg was working for an escort service and was hired by Montgomery County businessman David Downey on July 30.

Downey said that Burg was alive when he called the escort service to pick her up about 24 hours after she arrived.

Ex-boyfriend David Tanczak said that he had seen Burg the same evening that she was taken to Downey’s home.

“Ashley was with me that night — with me, my girlfriend, my little sister. She said she was going to meet with her sister … I had nothing to do with this. It’s a shame what happened to Ashley, and I really did care for her,” Tanczak said.
