MIDDLEBURY, Vt. (AP) — Police said Monday they've been investigating a link between the 1971 disappearance of a Middlebury College student and millionaire murder suspect Robert Durst.

Investigators have been aware for several years of a link between 18-year-old Lynne Schulze and Durst, who operated the All Good Things health food store in the town, the Middlebury Police Department said in a statement.

Schulze, a native of Simsbury, Connecticut, who entered Middlebury College as a freshman in September 1971, was last seen that December. Her missing-person flyer shows her peering serenely through a loosely parted mane of light-brown hair.

The Schulze case was reopened in 1992 and has continuously generated leads, police said.

Middlebury police call it an ongoing criminal investigation and say they aren’t releasing any other details.

The 71-year-old Durst is a member of a wealthy New York real estate family that runs 1 World Trade Center. He’s charged with killing a woman 15 years ago in Los Angeles. He’s been ordered held on weapons charges in Louisiana, where a judge decided he’s a flight risk and a danger to others after considering what FBI agents found in his hotel room — an elaborate disguise and other escape tools fit for a spy movie.
