Two LSU graduate students died Sunday after they were found earlier that morning unresponsive at the bottom of a swimming pool in a Tigerland-area apartment complex, Baton Rouge police said.

When police arrived at the Cambridge West Apartments, 1315 Bob Pettit Blvd., at about 1 a.m., they found Anton Joe, 25, and Ishita Maity, 28, at the bottom of the pool, police said. An officer went into the water and pulled them out, but both were unresponsive, police said.

Joe and Maity were taken to a hospital where they died Sunday afternoon, said Cpl. Don Coppola Jr., a police spokesman.

Police said the pool was closed and a gate to get into it was locked Saturday night and early Sunday morning. The two apparently got inside by climbing over a fence around the pool, police said.

“At this time there are no obvious signs of foul play,” Coppola said Sunday afternoon.

Joe was a third-year graduate student in physics, and Maity was a second-year graduate student in physics, said Ernie Ballard, LSU media relations director. Both students were pursuing their doctorate degrees, he said.

The Cambridge West apartment building is one of three Cambridge properties on Bob Pettit Boulevard off Nicholson Drive. Joe lived in that building, and Maity lived at another Cambridge apartment building at 1221 Bob Pettit Blvd.

The neatly landscaped apartment complexes are each surrounded by a tall, security fence with resident-only access. At Cambridge West, the pool, in the center of the complex, is also surrounded by a tall, head-high fence.

On Sunday afternoon, there was little traffic in or out of the complex and no one was in the pool. There was virtually no activity outside and nothing to indicate the early morning tragedy.

The investigation is continuing, police said.
