A Wichita man who stabbed a 69-year-old woman to death inside her home is going to prison.

 

Marrell Tisdale, 24, pleaded guilty last September to second-degree murder in the death of Gertrude Lott, his grandmother. Tisdale also admitted to aggravated battery for going after his mother with a meat cleaver. His mother was not seriously hurt.

 

When police arrived at the home in the 3100 block of E. Stadium Drive on the morning of Feb. 3, 2011, Tisdale had cut his own neck. 

 

Tisdale suffers from paranoid schizophrenia. Judge Eric Commer sentenced him to 17 years and four months behind bars, where he will be treated for his mental illness.
