EDWARDSVILLE, Ill. – Police are asking the public for help finding a man suspected of abducting his 13-year-old stepdaughter and her 2-week-old son.

Investigators believe 39-year-old Christoper M. Derleth kidnapped Katherine Elizabeth Derleth and her newborn son, Christopher Ray Derleth.

The teen and her son were last seen Sunday at the home of a guardian in suburban Edwardsville, Illinois.

“We are asking for assistance from authorities from here all the way to the East Coast,” said State’s Attorney Tom Gibbons. “We believe they may be in West Virginia or somewhere along the way.”

Christopher M. Derleth has been charged with aggravated kidnapping, a Class X felony, for allegedly taking the baby out of the state of Illinois.

Police believe the teen and her baby may be in danger.

“A 19-day-old child needs medical care that I don’t think a 13-year-old is prepared to deliver,” said Sheriff John Lakin. “I think we also have to look at the situation that a 13-year-old old young lady delivered this child 19 days ago, and she may need medical care, as well.”

Police issued a nationwide warrant for Christopher M. Derleth’s arrest.

It is believed that they are heading to West Virginia, where an Amber Alert is in effect.
