A former student at a Connecticut boarding school says that more than 30 years ago, he buried a coffee can of pornographic photos that would help prove a teacher sexually abused youngsters.

Lawyers descended on the Indian Mountain School with shovels last fall in an unsuccessful effort to find the material. They may return and dig some more when the ground thaws this spring.

The teacher under suspicion is now dead. The ex-student says the teacher took sexually explicit photos of students.

A school spokeswoman says an independent investigation is continuing.
