A former stay-at-home dad who worked at home, Bob Weiss had an especially close relationship with his 19-year-old daughter, Veronika. He knew something was amiss Friday night when Veronika, who frequently checked in, didn’t call her family.

So he tracked Veronika’s cell phone online.

“We got on her iPhone and located it in the middle of the crime scene,” Weiss said.

The phone was moving, but no one was answering.

“We actually were looking at her phone while they were moving her body … probably to take her to the morgue.”
