In response to several local high-profile cases of domestic violence, a Waltham-based prevention organization is holding a forum to address residents’ concerns Monday from 6:30 to 8:30 p.m. in the McDevitt Middle School auditorium, 75 Church St. The nonprofit REACH Beyond Domestic Violence cited the August murder of Jennifer Martel, allegedly by her boyfriend Jared Remy, son of Red Sox broadcaster Jerry Remy, as well as the arrest of Boston Celtics forward Jared Sullinger for allegedly assaulting his girlfriend in their Waltham town home as prompting the discussion. Executive director Laura Van Zandt also noted the conviction of former Waltham police chief Thomas LaCroix this summer on charges that he twice attacked his wife in their Maynard home. The forum will emphasize prevention methods and resources to help stop domestic violence, and steps that bystanders and victims can take, she said. Van Zandt said the forum will not be a “rehashing” of the recent cases, but rather an informational session sparked by them. There will be a panel of four professionals who will take questions from the audience: Emerge abuser-education specialist David Adams; a Waltham police officer, Detective David McGann; REACH Beyond Domestic Violence official Jessica Hollander; and a Middlesex district attorney’s office representative, Shawn MacMaster. To submit a question to the panelists in advance, contact Allison Reynolds-Berry at firstname.lastname@example.org or 781-891-0724, ext. 107. For more information, visit www.reachma.org.
