Crime Police Identify All 7 Victims of Suspected Connecticut Serial Killer Authorities suspect current Connecticut inmate William Devin Howell is behind the slayings By Tara Fowler Published on June 9, 2015 09:05 AM Share Tweet Pin Email Trending Videos Photo: SOCDOCJ All seven bodies discovered behind a shopping center in New Britain, Connecticut, have been identified. Police believe that the seven individuals were all victims of a single serial killer, though they have declined to publicly comment on the name of a suspect, CBS News reports. However, a source close to the investigation has said that authorities suspect William Devin Howell, a 45-year-old Connecticut prison inmate currently serving a sentence on unrelated manslaughter charges, is behind the slayings. If it turns out that he is responsible for all the deaths, it would make him one of the state’s most prolific serial killers, rivaling Michael Ross, who was executed in 2005 after he confessed to killing eight women and girls in the 1980s. The seventh victim was identified Monday as Marilyn Gonzalez, 26, a mother of two who vanished in 2003, New Britain Police Chief James Wardwell told CBS News. “Today, Marilyn Gonzalez would be a grandmother to an 8-month-old little girl if Marilyn had not fallen victim to an apparent serial murderer,” Wardwell said. “She was a sister, a daughter and a mother,” he continued. “Marilyn has family who loves her and misses her.” Gonzalez joins six other victims identified as Diane Cusack, 53, Joyvaline Martinez, 23, Mary Jane Menard, 40, Melanie Ruth Camilini, 29, Danny Lee Whistnant, 44, and Nilsa Arizmendi, 33.
