ARLINGTON, Mass. (WHDH) -- A former Arlington selectman is facing charges after teenagers were drinking at her house, according to police.

Police said the house of former selectman, Annie LaCourt, and her husband was the site of a raging teen drinking party Friday night.

Neighbors awoken by the ruckus saw packs of kids out in the street around midnight.

Police said an officer on patrol discovered a drunken high school boy urinating on school property across the street from the LaCourt house which led them to the party. Officers found more than 30 underage kids, many holding red solo cups.

“Twenty-three failed the sobriety test who were underage,” said Kevin Greeley, Arlington board of selectmen chair.

Greeley stressed the investigation is preliminary, but now police want to know how the kids obtained the alcohol.

Investigators said LaCourt, once a member of the board of selectmen and a proud democrat who stepped down this year was home with her husband.

“She’s done an outstanding job as a member of the board of selectmen. But it would be very, very disappointing to have a public official, community leader involved in an incident such as this,” said Greeley.

According to a family website, the LaCourts have two daughters. Police investigated teen drinking at this home three years ago when the older daughter was 17.

LaCourt's husband explained to 7News that back then his wife was upstairs and unaware kids were allegedly playing beer pong on the first floor.

“There was no evidence that there was any organized mass drinking going on here. It was a couple of beer cans. That’s it,” said Mark Burstein, LaCourt’s husband.

Arlington police said they are contemplating charges against LaCourt and her husband, but the investigation is ongoing. Massachusetts has a social host liability law that says you can get a $2,000 fine after a year in jail.
