Cpt. Tony Arpacz of the State Police and Janet Tessier, half-sister of Jack McCullough, answer questions from a media outlet following a post-verdict press conference. Tessier testified against McCullough during the trial, saying her mother, Eileen Tessier, told her she knew McCullough was responsible for the 1957 kidnapping and murder of Maria Ridulph, 7. Tessier said she sent an email to the State Police with a tip about Ridulph’s murder and Arpacz responded. She said Arpacz and his investigative unit were eventually responsible for solving the case.
