The Kathleen Anderson murder in December 2018 shocked the quiet neighbourhood of Menlo Park, California. “The Tech Bro Murders: Killer Code” is a true-crime documentary that looks into the case again, going over the events, the strange circumstances and the disturbing reason behind the crime. The show also looks back on Kathleen’s extraordinary life and how her tragic death terribly affected her family and friends. People were very interested in this case because it was so brutal and because the killer had strange beliefs. As part of their coverage of true-crime stories, platforms like Spiky TV continue to discuss the case.
Who was Kathleen Anderson?
Kathleen Hughes Anderson was a lively woman whose life was full of meaning and passion. She was born in Decatur, Illinois, but moved to California in the 1980s to attend college. Kathleen was a dedicated arborist who worked for the town of Atherton starting in 1989. Her love of trees and landscaping showed through in her work. She took pride in transforming spaces, such as her Menlo Park home, where she cultivated a beautiful garden.
In the late 1970s, Kathleen and Billy “Andy” Anderson tied the knot and established a fulfilling life in California. Billy owned Dahl Plumbing in Palo Alto, and their partnership was based on love and support. Kathleen formed a close-knit group of friends, despite never having children. She was devastated after Billy died in 2007, but she found the strength to keep going. She retired in 2011 and spent her days doing things she liked, like trying out new relationships, including one with her friend Daniel Baggett.

The Tragic Night of December 12, 2018
Kathleen’s life came to a terrible end on December 12, 2018. Daniel Baggett, her friend, called the police to check on her because he thought something was wrong. When the police got to her Menlo Park home, they found a horrible scene. Kathleen, who was 62, had been attacked very badly in her basement. She had been stabbed, almost had her head cut off, and had a pen stuck in her eye. The crime’s brutality shocked the community and left police looking for answers.
The police found Daniel Baggett at the scene, holding a knife to another man’s throat. The man was Francis Wolke, a 30-year-old computer programmer who had never met Kathleen before. Baggett explained he felt an inexplicable urge to visit Kathleen’s home, where he found Wolke with her body. He restrained Wolke until the police arrived, a move that likely prevented the killer from fleeing.
Who Is Francis Wolke?
The story of Francis Wolke makes this tragedy even more upsetting. Wolke moved to Silicon Valley in 2014 from Cincinnati to pursue his dreams of success in the tech industry. He worked as a programmer, mainly on an operating system, but his career went downhill when he lost his job. He lived on the streets in California for six months before going back to his parents’ house. Wolke came back to the Bay Area only two days before the murder.
Wolke admitted to the murder during police questioning and gave a shocking reason for it. He said that hearing voices and having delusions made him think that doing a ritualistic sacrifice would make him rich and keep him young forever. He said that he went into Kathleen’s house, tried to strangle her and then used a pen and a hacksaw to carry out the horrible attack. Wolke didn’t know Kathleen personally, which makes the crime even more terrifying because it was random.
The Investigation and Trial
It was hard to find Kathleen’s killer. Wolke’s confession helped clear things up, but his unusual statements about hallucinations and ritualistic purposes made some wonder if he was mentally stable. The police learnt that he had been at Kathleen’s house for hours after the murder. If Baggett hadn’t stopped him, he might have gotten away.
Wolke’s trial began in March 2023. His lawyers argued that he was not guilty due to his insanity, citing his delusional beliefs and psychotic condition as evidence. Lawyers claim that he wasn’t in charge of his actions because of his mental state. But the jury didn’t buy this defence and found Wolke guilty of murder in the first degree. He was sentenced to 26 years to life in prison, with over 1,600 days credited for time served. At 33 years old, Wolke won’t be eligible for parole until 2036.

Where is Francis Wolke now?
Francis Wolke is serving his time for killing Kathleen Anderson in September 2025. Recent records show that he is “out to hospital“, which means he is getting medical care, possibly for his mental health claims. Wolke remains an intriguing person, even in jail, due to the shocking nature of his crime and the reasons he provided for it. Many people are still trying to make sense of Kathleen’s death, so his eligibility for parole in 2036 will probably bring this case back into the news.
Documentaries like The Tech Bro Murders: Killer Code keep bringing attention to cases like this one by showing how investigations work and how violent crime affects people.
