SHILOH, Mo. (AP) — A 19-year-old woman has been charged with kidnapping an elderly man who let her into his home when she came to his door asking for help.

KSDK reported Thursday that Brittany Davis is charged with kidnapping and aggravated battery. A man is also in custody but has not yet been charged.

The St. Clair County prosecutor says the 77-year-old victim let the woman into his home near Shiloh Saturday night. Once inside, she let a man in through the back door.

The suspects allegedly tied the man up after robbing him. They then forced him into the trunk of his car and drove him a few blocks away, where he was able to free himself and get out the trunk.
