They are Susan and Keith Macferran of 5 W. Second Ave.
Police said both died from gunshot wounds. It appears that Keith Macferran, 48, shot his wife, Susan, 62, while she was asleep Sunday, then turned the gun on himself.
Both were found in the couple's bedroom.
Newspaper records indicate the couple was married in 1991. Mrs. Macferran worked in food service for Hempfield School District, at Rohrerstown Elementary School.
Susan Macferran's son discovered the couple Tuesday when he went to the home, police said.
Lititz Police were assisted by the Lancaster County Crime Scene Forensic Unit, the Lancaster County District Attorney's office and the Lancaster County Coroner's office.
Autopsies are being done today. Additional details will be released when they are available, police said.
