FORT WORTH (CBSDFW.COM) – The Tarrant County Medical Examiner revealed Sunday 36-year-old Shanna Vandewege died from a cut to her neck similar to the wound that killed her infant son.

The news only adds to the tension in an already anxious neighborhood.

The crime scene was visible from Teri Perez’s own house.

Police taped off the area and collected evidence Friday after finding 36-year-old Shanna Vandewege and her three-month-old son dead. The investigation unfolded right next to the bus stop where Perez’s children arrived from school that afternoon as Perez left work early to meet them after hearing the news.

“On Friday I called them en route, and I was like, lock the doors, turn on the alarm, and don’t answer the doors at all. It’s very scary,” Perez said.

Investigators have interviewed the husband and father of the victims, Craig Vandewege but say they have not named any specific suspects.

Neighbors like Jim Brockway are eager to know who is responsible.

“Normally on something like that they start looking at people that are familiar with the family to begin with, but I’d be more concerned if I find out that it was just random,” Brockway said.

Even as new information develops, neighbors are still left with a nagging sense of uncertainty.

“It totally flips my thinking, and so now I’m kind of more on edge because not knowing any suspects,” Perez said.

Fort Worth police say Craig Vandewege is cooperating with the investigation. They also say all options and leads are being investigated.
