Diederick Jonas Vandewege, aged 3 months, was killed on December 15, 2016, along with his mother, Shanna Vandewege, in their home in Fort Worth, Texas. Their bodies were discovered by the authorities after Craig Vandewege, Shanna's husband and Diederick's father, made a 911 call claiming that someone had broken into their house and killed his family. Both Shanna and Diederick were found with their throats slit, and the crime scene appeared to have been staged as a burglary, with drawers left open and items knocked over. However, investigators soon determined that the scene did not align with the typical behavior of a burglary, particularly because an infant was also killed, which they found highly unusual for a home invasion scenario.
Craig Vandewege became the prime suspect after inconsistencies in his statements to police and suspicious behavior were noted. Investigators found that he stood to gain over $700,000 in life insurance following the deaths of his wife and son, adding a potential financial motive to the crime. Additionally, when Craig was stopped by law enforcement in Colorado a few days after the murders, he had several loaded firearms, ammunition, and medication in his vehicle. His demeanor during and after the incident further raised suspicion, as he seemed unusually calm for someone who had just lost his family in such a brutal manner.
After a lengthy investigation and a trial delayed by several years due to the COVID-19 pandemic, Craig Vandewege was found guilty of the murders of his wife and son in 2021. He was sentenced to life in prison without the possibility of parole, providing some measure of closure to Shanna's grieving family, who had endured years of uncertainty and distress while awaiting justice for their loved ones. The case has been widely covered and serves as a grim reminder of the complexity of domestic violence and the potential hidden dangers within seemingly ordinary families. Craig Vandewege remains incarcerated, serving his life sentence in Texas without the possibility of parole.
The verdict brought some solace to Shanna's family, including her father, Mark Riddle, who expressed relief at finally being able to put his mind at ease after a long and difficult wait for justice for his daughter and grandson. The tragic incident was also featured in media coverage, including an episode of Investigation Discovery’s "American Monster," which documented the events leading up to the horrific crime and the subsequent investigation.
