KANSAS CITY, Kan. -- Prosecutors have upgraded the charges against a Kansas City, Kan., man in connection with the death of a 10-month-old.

The Wyandotte County, Kan., District Attorney charged Anderson Cheffen, 31, with first-degree murder on Tuesday.

Cheffen was originally charged with child abuse by Wyandotte County prosecutors. Court records state that Cheffen lived with the baby's mother at a house near 98th Street and Kansas Highway 32 in Edwardsville.

"To know, and to think it happened just two door down from me," a concerned neighbor said. "But I feel for the child, too. A child like that has no defenses, you know."

Cheffen remains in custody in the Wyandotte County Jail in lieu of $1 million bond.
