A Shed Across from a Prison. A Skeleton Inside. Now Cops Say It Was a Fugitive Sex Offender Missing for Years

The human remains of a sex offender have reportedly been found.

According to ABC affiliate WMTV, police were alerted about the remains on April 21 after a man found the materials in a shed across the street from the New Hampshire State Prison.

Per ABC affiliate WMUR, on Monday, May 5, an autopsy said the remains belong to 59-year-old Michael Schilz. The Department of Corrections confirmed that Schilz was a convicted sex offender on parole.

According to reports, the remains had likely been at the location for a while.

Per the Concord Monitor, Lt. Thomas Yerkes said that it was possible the remains have been in the area for as long as years due to the condition of the skeletons.

A cause of death has currently not been determined and charges have not been made yet, Yerkes told the outlet.
