Man sentenced to prison in stabbing death of his grandmother

A Wichita man who suffers from paranoid schizophrenia was sentenced Friday to 17 years and four months in prison for the stabbing death of a woman he knew as his grandmother.

Marrell Tisdale, 24, who had no criminal record, told police he killed Gertrude Lott, 69, on Feb. 3, 2011, because he thought it would give him the strength he needed to kill himself. Tisdale had a self-inflicted cut to his neck when Wichita police found him sitting on a couch in a home he shared with his grandmother at 3101 E. Stadium.

Tisdale pleaded guilty in September to second-degree murder in the Feb. 3, 2011, death of his grandmother and aggravated battery for attacking his mother with a meat cleaver the same day. She was not seriously injured.

In following a plea-agreement, District Judge Eric Commer sentenced Tisdale to 165 months on the murder charge and 43 months on the aggravated battery charge, then ruled that the sentences should be served consecutively. Commer said a report from a psychiatrist at the Larned State Hospital indicated that Tisdale’s mental health issues could be managed in prison.
