Police later arrested and charged David Okoroji after he allegedly confessed to the killing, Monroe said.
He is charged with first- and second-degree murder, first-degree arson and a charge related to use of a dangerous weapon. No attorney was listed Friday in court documents for Okoroji.
Okoroji allegedly told police that he stabbed Cheeks four or five times with a large kitchen knife. The woman begged him to stop during the attack, Okoroji allegedly told police.
He then said he used a newspaper and a lighter to start the fire. After the attack, Okoroji allegedly went to another location where he took a shower and threw away the bloody clothing in the trash, Monroe said.
