A memorial service for the three University of Maine fraternity brothers killed in a plane crash in Owls Head this month is planned for the school’s Orono campus. The service scheduled for Tuesday night was organized by the university’s Interfraternity and Panhellenic councils. It will take place in the Hauck Auditorium and will be followed by a candlelight vigil on the university mall. Members of Lambda Chi Alpha fraternity will eulogize the two students killed – 22-year-old David Cheney of Beverly, Mass., and 24-year-old Brazilian exchange student Marcelo Rugini – as well as 2011 graduate William “B.J.” Hannigan of Portland, the pilot of the plane. The students’ single-engine plane crashed on takeoff from the Knox County Regional Airport on Nov. 16. The cause remains under investigation.
