Emmett’s parents write that he was a recovering alcoholic and had been sober for two years before he went off to college in August 2014.

“Within 6 weeks, heroin came into his and our lives, stole him from us and Substance Use Disorder killed him in only 18 months,” the obituary states.

The college sophomore’s casket was carried into Bridgewater’s Central Square Congregational Church on Wednesday. Inside, his father talked about why he wants everyone to know about Emmett’s struggle.

“Our honesty and openness in this obituary was so that other parents could follow suit without shame or embarrassment,” Bill Scannell said.

Emmett’s family says their public plea, shared more than 3,000 times so far on Facebook, is already making an impact.

“A close friend of mine whispered in our ear that because her daughter who had been a heroin addict and substance abuse sufferer saw Emmett’s story, they were leaving right here from the funeral to check her into detox immediately,” Bill Scannell told CBS News.
