Police again ask for help in solving Lancaster slayings

LANCASTER - The person who stabbed to death a couple and their son may have injured his or her hand, arm or another body part, police said yesterday in a new appeal for the public's help in solving the crime.

Also, the killer may have lied about his or her whereabouts from 1 to 3 a.m. Saturday, when Thomas and Lisa Haines and their teenage son, Kevin, were slain in their home, Manheim Township police said. "If you know this person, you may not think they are capable of this type of crime," police said in a news release. "They may also have fabricated an alibi concerning their whereabouts during this time frame. They may not have a prior record of violence."

Chief Neil J. Harkins said investigators were working on tips. He previously said there were no suspects, but yesterday was less specific.

"The best I can tell you right now, the fair thing to say, is we're still working on leads, promising leads," he said. - AP
