Authorities say corrections officer Winlaw Muzirwa walked into the Tinicum Township police station on Wednesday morning and asked to be put in handcuffs. Delaware County District Attorney Jack Whelan says Muzirwa soon confessed to killing his wife, Daisy Janbawo.
Investigators say shortly later they discovered Janbawo shot in the head and back in an upstairs bedroom of the couple's home.
Court documents say Muzirwa tried to kill himself after shooting his wife but the weapon misfired.
Muzirwa had been on disability leave from his job with a private company that operates the county prison. Court records don't list an attorney for him.
