DNA evidence collected from an open whiskey bottle was crucial in securing the conviction of a man from Lunenburg who was involved in a knifepoint rape incident in Acton back in 2013.

Christopher Aldrich, now 30 years old, received a 15-year prison sentence on Tuesday, as confirmed by Middlesex County District Attorney Marian Ryan in a statement.

According to the statement, Aldrich fled the scene after assaulting the unnamed woman at the South Acton Commuter Rail station. Authorities struggled to locate him and noted that there were no nearby surveillance cameras to assist in the investigation.
