A Sedgwick County teenager has now been charged with second degree murder in the shooting death of his mother last year at their home near Andover.

The 15-year-old boy was originally charged with voluntary manslaughter in the June, 2018 death of 41-year-old Lisa Trimmell.  She was found dead in her home in the 3200 block of North 159th Street East.

Defense attorneys have said that the teen was acting in defense of himself and his younger brother.  The attorneys said that Trimmell had been psychologically and physically abusive toward her two sons, and she had a high blood alcohol level at the time of her death.

Defense attorneys filed a motion to dismiss the charge.  A status conference is scheduled for October 29th and a hearing on the motion to dismiss has been scheduled for January.
