WICHITA, Kan. (KWCH) -- The son of a Sedgwick County woman accused in his mother's death is now charged with second-degree murder.
An amended complaint filed Monday upgraded the charge from voluntary manslaughter to second-degree murder in the shooting death of Lisa Trimmell.
Due to the amended charges, Tuesday's first appearance was rescheduled. The defense filed a motion to dismiss to the manslaughter charge but must now apply that motion to the new charge.
An immunity hearing for the new motion to dismiss is scheduled for January 21-27, 2019, beginning at 8:30 a.m. A status conference is set for Oct. 29.
Lisa Trimmell, 41, was found dead in June 2018, at her home in the 3200 block of North 159th Street East, near Andover.
Attorneys for the teen say Trimmell was an alcoholic for several years. They say it led to her being psychologically and physically abusive towards her two sons who were 12 and 14 at the time of her death.
The teen's attorneys say he feared for his younger brother's life and fetched a loaded gun his mother kept in the home then shot her in the neck. The teen then called 911, but Trimmell died on the scene.
Attorneys for the teen say Trimmell had a blood alcohol level of .185 at the time of her death. That's more than twice the legal limit to drive. They say their client acted in self-defense.
