Less than a year after the massacre at Columbine High School, two sophomores were found shot to death today in a sandwich shop near the school.

The bodies were discovered just before 1 a.m. when an employee of the shop happened to drive by, noticed lights still on almost three hours after closing time and went inside to see why. The authorities said she found the bodies behind the counter. They were later identified as those of Nicholas Kunselman, 15, an employee of the shop, and Stephanie Hart, a 16-year-old girl he was dating.

A spokesman for the Jefferson County Sheriff's office, Steve Davis, said investigators had determined neither a motive for the shootings nor a time of death, although they ruled out a murder-suicide.

Mr. Davis said they had no suspects but wanted to question a white male in his late teens or early 20's wearing a red jacket and flared pants, whom the employee said she saw leaving the area when she arrived. He said investigators were also reviewing videotape from a surveillance camera inside the shop.
