MERRIMACK — Merrimack police arrested a local family after they allegedly stole a Hillsborough County Superior Court Probate file, then posted a video of the file on YouTube.

Merrimack police said they received an anonymous tip on Wednesday that Michael Gagnon, 42, Karen Gagnon, 44, and their son Andrew Lemieux, 24, all of Unit 524 at the Residence Inn in Merrimack, had posted a Youtube video with the missing file at the family's previous home at 52 Naticook Road in Merrimack, which has been empty since a fire rendered the dwelling uninhabitable in 2009.

Merrimack police said the Gagnon's and their son make admissions on the "You Tube" video that the file they are seen displaying is a court file that was the property of the Hillsborough County Superior Court, which they removed from the courthouse on Spring Street in Nashua.

Karen Gagnon, Michael Gagnon, and Andrew Lemieux were each arrested and charged with receiving stolen property. Police recovered the original probate court file from the Gagnon's room shortly after they were arrested.

All three have been released on $1,000 personal recognizance bail and are due back in the 9th Circuit Court in Merrimack on February 26 at 8 a.m. for arraignment on the misdemeanor charges.
