A Bradenton man is behind bars charged with the murder of his mother and her boyfriend. Family members tell 10 Investigates that while Thomas Matejcek sits in a jail cell, he’s refusing to take his court-ordered medication. They worry that once again, he’ll be ruled incompetent and worry he’ll be back on the streets. Matejcek was arrested in November and charged with two counts of first-degree murder. Manatee County deputies were called just after 12 p.m. on Nov. 10 about a disturbance in the Arbor Terrace RV community on 55th Avenue West in Bradenton. According to the sheriff's office, neighbors heard a woman screaming for help and called 911. Deputies said they arrived to find 62-year-old Patricia Matejcek and her boyfriend, 55-year-old Sean Harrison Sr., dead on the floor of a home. Patti Matejcek’s sister, Krista Kale, who is also Thomas’s aunt told 10 Investigates in February that her nephew was behind bars two years ago for strangling his mom, but he was let out of jail after being ruled incompetent. Now, they wonder what can happen if he refuses to take the meds prescribed to keep him competent as he faces two first-degree murder charges. Kale shared with us her nephew’s medication logs for a few weeks. The records show that after returning to jail from a treatment facility, he refused his medication almost every single day.
