A mother and her baby boy found dead in bed late Thursday at their home in far North Fort Worth were both victims of a homicide, authorities say.

Both 36-year-old Shanna Vandewege and 3-month-old Diederik Vandewege had their throats slashed, a Tarrant County medical examiner's report indicates.

The Fort Worth Police Department's homicide unit is leading the investigation, police spokesman Daniel Segura said. No further details were released Saturday.

"At this time we have ruled no one out as a potential suspect," police spokesman Jimmy Pollozani told KXAS-TV (NBC5). "Also we are not specifically looking at any one person as a suspect."

Fort Worth police said a man called 911 about 9:30 p.m after he arrived home in the 8500 block of Cactus Flower Drive and found his wife and child dead.

The medical examiner determined that each of them died from an "incised wound" to the neck, meaning it was caused by a sharp instrument like a knife.

Police said the husband, Craig Vandewege, was cooperating and that they had not yet identified any suspects.

Mark Riddle, Shanna Vandewege's father, told the Fort Worth Star-Telegram that his daughter was ecstatic about welcoming her first child in August after suffering three miscarriages.

Riddle, who lives in Colorado, said he'd been in Texas for the birth of baby Diederik and that he and other family members were looking forward to seeing the family next week when they'd planned to visit for Christmas.

Riddle said Craig Vandewege, who works at Costco, had moved from Colorado to Fort Worth first to find the family a home earlier this year before Shanna Vandewege, a registered nurse, joined him.

"They picked out the neighborhood that they thought was one of the best neighborhoods they could find," Riddle said. "Apparently it wasn't."

Loved ones took to Facebook on Friday as they began to hear about the death of Shanna and Diederik Vandewege.

Cindy Prevatt posted several photos and said, "I love you Shanna Riddle Vandewege and precious baby boy, RIP ... We will miss you so much."

Brianna Ayala, an 18-year-old who lives down the street, told the Star-Telegram that she noticed commotion when she left to get food about 10:30 p.m.

"They [the police] didn't come blazing in," she said. "They were quiet; that's what made me think something had already happened."
