TOPEKA, Kan (WIBW) -- Shawnee County prosecutors say they can tie written murder confessions back to the man charged with killing his mother. The preliminary hearing for Jason Hachmeister began Friday (9/7). He's accused of killing his mother Sheila.
Sheila Hachmeister was found murdered in her home at 3520 SW Belle, in Topeka, in the home she shared with her son Jason, in September 2011.
Investigators say they found the 58-year-old face down in her living room, with a startling 98 wounds, more than 15 of them from being stabbed, likely with a steak knife. But the blows to her head, and severe defensive wounds didn't kill her, so the person strangled her to death.
Investigators compiled more than a dozen handwritten letters that include specific details, details prosecutors say would only be known by the real killer. Detectives say the letters were written in code, with the key included. The author claims to be the murderer, saying he spotted Sheila at a local bar, hit on her, and became angry when she turned him down. The author writes that he followed her for several weeks, then waited in her house until she arrived, saying he "hit her until she shut up," then took his rope out and finished her.
The letters were sent to Topeka Police detectives, and to an attorney, via a third party. Investigators say at least one of the letters was traced directly back to Jason Hachmeister, who was behind bars at the time. Investigators pointed out the striking similarities in each letter, for instance, each one was signed "bye bye."
Jason made the 911 call the day of the murder. Detectives say Jason was calm, clear and not emotional in that phone call. They say he didn't ask for help. He was arrested for the crime three months later at the Hooters in Topeka.
Investigators say DNA evidence found in blood on a hand towel, blood on a bathroom faucet, and on the rope around Sheila's neck was a match to Jason and his paternal relatives.
The preliminary hearing continues Thursday, Sept. 13th. Jason Hachmeister also faces 113 counts of possessing child pornography in a separate case. A motions hearing in the child porn case is set for November 2nd.
