Marvin Marney lives next door. He says De Anda, along with her husband and two children just recently moved in.

Marney says he didn’t have much interaction with the couple, but at one point did hear a disturbing argument taking place at the home.

“I heard something one day but it was real brief, so I just kind of didn’t pay it too much attention after that. But now that I think about it I should have said something” he said.

“We are committed to a very thorough investigation to make sure we establish who committed this crime and provide answers for her family and loved ones,” Chandler said.
