ROCHESTER - The investigation into a decades-old alleged sexual assault on a minor against former city councilor Doug Lachance appears to be winding down.
Rochester Police have been investigating the case against the former city councilor and mayor since early March.
Strafford County Attorney Tom Velardi told The Rochester Voice on Thursday that he got the "final submission from RPD last week."
Lachance, 57, officially resigned his City Council seat on April 14 about a month after police say they reopened a sexual assault investigation from 2007 that involved a 16-year-old boy.
Lachance has denied the allegations and did so again in his resignation letter.
In a 2007 police affidavit, Andy Brooks, 37, of Colorado, who grew up in Rochester, alleges Lachance made inappropriate sexual advances to him when Brooks was a teenager.
Brooks told investigators in 2007 that most of the alleged abuse occurred in the spring of 2001.
The 2007 case fizzled after the main complainant - identified as Brooks in a police affidavit - decided not to move forward with the charges.
Lachance on Tuesday indicated to The Rochester Voice he still had no comment.
