DES MOINES, Iowa (AP) -

An April trial has been scheduled for a 42-year-old man charged with killing his former roommate in Des Moines.

The Des Moines Register says Lavelle McKinley pleaded not guilty Thursday to a charge of first-degree murder. The trial is set to begin on April 24.

The body of 47-year-old Cynthia Rouse was found by her husband in her apartment on Jan. 14. Police say McKinley lived with Rouse briefly before her husband returned from a work-release program.

Authorities have not released a cause of death.

McKinley remains in the Polk County Jail.
