LAS VEGAS — A man stabbed to death last week on a Las Vegas Strip pedestrian walkway was identified Tuesday as a homeless ex-convict from Pennsylvania dubbed the “pantyhose prankster” and sentenced to prison for making lurid telephone calls to women in several Eastern states.

Rip Alan Swartz, 46, made thousands of random calls to banks, restaurants and other numbers he found in telephone books before he provided his real name to a Virginia woman and was arrested in 2011, said Detective Sgt. Thomas Kauffman, of the Upper Allen Township Police Department in Pennsylvania.

“That guy he was one of the strange ones,” Kauffman recalled Tuesday.

Swartz’s name became public as his alleged assailant, Calvin Boyden III, 22, of Las Vegas made an initial court appearance on felony murder and robbery charges in the 12:40 a.m. Nov. 25 slaying on a foot bridge over Las Vegas Boulevard near the multi-hotel CityCenter complex.

Boyden was being held without bail at the Clark County jail. He plans to plead not guilty, an attorney said.
