Police say a Tennessee man is accused of beating an infant to death after discovering that he wasn't the child's father.

Memphis police say 33-year-old Jose Avila-Agurcia is charged with murder in the death of 4-month-old Alexander Lizondro-Chacon.

News outlets cited an affidavit of complaint that says officers responded April 12 to a report of an unresponsive infant. The baby was taken to a hospital and later pronounced dead from blunt force trauma to the head.

The affidavit says Avila-Agurcia became a suspect after the child's mother, Mercy Lizondro-Chacon, told investigators that the man said he struck the baby multiple times in anger after learning he wasn't the father.

Avila-Agurcia is being held at a county jail.

It wasn't immediately clear whether he has an attorney.
