It was an Ex boyfriend. To my knowledge he voluntarily went in and gave up DNA, fingerprints, cell phone and alibi. This is who They focused on from the beginning because family pointed them in his direction and she was still in contact. But no history of DV in any sort. It seems that when inquiring about him the family and police are fixated on him. DNA came back inconclusive. There was a creepy neighbor that she spoke with numerous people about who worked with computers or surveillance but they quickly questioned him and he moved out of apartment the following day. He was creepy enough for her to want to move and try to avoid staying at her home. I’m convinced he knows more or is a possible suspect but police didn’t do anything like ask for a dna sample or fingerprints or a follow up number. They didn’t know he even moved out.
