Authorities are hoping the beefed-up law enforcement will lead to clues that will solve the slayings at the Subway outlet, the sheriff's department confirmed. It also was learned Wednesday that federal and state officials soon will launch a formal investigation into labor practices at the Subway where the bodies of high school sweethearts Nick Kunselman and Stephanie Hart were found on Valentine's Day. Officials are trying to determine whether the sub shop violated federal child-protection labor laws that prohibit anyone under age 16 from working after 7 p.m. during the school year. He declined to specifically comment on the case. The store's owner, Joseph Hartman Jr., could not be reached for comment.
Investigators continue to look for a young man who was seen near the shop that morning.
Drawings of the young man show him as clean-shaven and wearing a black baseball cap. Authorities believe he's 16 to 18 years old, and said he also was wearing a black coat with a red lining or a red shirt or sweater, black or blue jeans and white shoes. He left on foot. Investigators have conducted more than 200 interviews and logged about 150 calls on a tip line since the start of the investigation. They've also received increased complaints in the Columbine area.
