Moviegoers in Harford County may be surprised to see a grim 30-second public service announcement before their regularly scheduled films, as county government embarks on another round of cautionary videos about the relentless heroin epidemic.A short PSA featuring Mara Finnegan, 11, of Forest Hill, who lost her sister to heroin on Christmas Day 2015, is playing at the Regal and Flagship theaters in Abingdon and Churchville, county spokesperson Cindy Mumby said.The county first added anti-heroin PSAs to its drug awareness initiatives in June.Those videos featured young teenagers from Street and Fallston, who lost relatives to the opioid that has claimed more than 29 lives this year in Harford County and caused more than 175 overdoses, according to the Harford County Sheriff's Office reports.The Sheriff's Office has said the tide of heroin deaths and overdoses seems to be continuing unabated, with numbers higher than last year's so far."This is the second of three anti-heroin PSAs produced by the Glassman administration to air in movie theaters," Mumby said in an email. "All three of these simple yet powerful messages feature Harford County children who have lost a loved one to heroin. The children have courageously stepped forward to raise awareness about this national scourge.""We have chosen the peer to peer format because it resonates with youth, and it has been recommended by experts in the field of juvenile drug prevention and by Maryland Governor Hogan's Heroin Task Force," Mumby wrote, adding that feedback has been "very positive" so far.The PSAs are set to run through Nov. 1 and reach an estimated 175,440 moviegoers, she said.The third round of the videos is in production. Those are expected to be released Oct. 1. The videos can also be seen on YouTube, by searching for Harford County, MD and HarfordCountyMD.gov.Mumby repeated a statement by County Executive Barry Glassman regarding the original initiatives: "We need to keep these conversations going because nothing is more powerful than parents talking to their kids about drugs."
