LANCASTER - Relatives and friends of three members of a family whose slaying remains unsolved will hold a memorial service at a Lancaster church tomorrow.

The service for Thomas and Lisa Haines and their son, Kevin, at Otterbein United Methodist Church will be closed to reporters and cameras will be banned, the Rev. Robert Bailey, the church's pastor, said yesterday. The Haineses were church members, and Thomas Haines had served as a trustee.

The three were stabbed to death around 2 a.m. Saturday by an intruder in their suburban home. A daughter, Bucknell University undergraduate Maggie Haines, fled the home at her mother's urging to summon help and was not injured.

Manheim Township Police Chief Neil J. Harkins said that police had no new breaks in the case. Profilers with the FBI are expected to be in Lancaster next week to help with the investigation.

An obituary published in the local newspapers Thursday described Kevin Haines, 16, as a very bright Manheim Township High School sophomore who wrote for the school newspaper and was working toward becoming an Eagle Scout.

Lisa Haines, 47, received a bachelor's degree in early childhood education from Elizabethtown College in 1981, taught preschool and Sunday school and enjoyed old movies, reading and animals.

Tom Haines, 50, spent more than 20 years at Motion Industries as a salesman and branch manager. He set school running records at Manheim Township High School before joining the track and cross country teams at Slippery Rock University, from which he graduated in 1978.

All three were Lancaster natives. A scholarship fund in their memory has been established in the Manheim Township School District.
