Mom's boyfriend charged with killing month-old Mo. infant

ST. JOSEPH, Mo. (AP) -- A St. Joseph man is jailed in the beating death of his girlfriend's 1-month-old baby.

Police say Steven Zorn beat the baby girl about the head, shook her, and dropped her to the floor early Monday at the home he shared with the child's mother. Paramedics and police found the baby, Cora Jean Lockhart, dead at about 9:15 a.m. Monday.

An autopsy showed the infant suffered skull swelling and fractures consistent with an assault.

Zorn is charged with felony second-degree murder and is jailed under a $500,000 bond in the Buchanan County Jail.

Zorn is scheduled to be arraigned Tuesday.

A family friend said Zorn lived at the home with the baby's mother, Susan Lockhart, and Lockhart's two other children. The friend said none of the children are Zorn
