What is the name of the person who attempts suicide?
In 2047, a distress signal is received from the Event Horizon, a starship that disappeared during its maiden voyage to Proxima Centauri seven years before and mysteriously reappeared in a decaying orbit around Neptune. The rescue vessel Lewis and Clark is dispatched to look for survivors and determine what happened. Captain Miller of the Lewis and Clark—along with second-in-command Lieutenant Starck, pilot Smith, medical technician Peters, engineer Ensign Justin, Doctor D.J., and rescue technician Cooper are also joined by Dr. William Weir. Dr. Weir, who designed the Event Horizon, briefs the crew on the ship's experimental gravity drive. The drive generates an artificial black hole and uses it to bridge two points in spacetime, reducing travel time over astronomical distances. The only message received from the ship after its departure was a strange recording of screams and howls. When the recording is filtered, Doctor D.J. believes he can make out the Latin phrase "liberatis me"  ("save me") being spoken amongst the screams.
Upon boarding the Event Horizon, the crew finds evidence of a massacre. As they search for survivors, the ship's gravity drive automatically activates. Justin is briefly pulled into the resulting portal. The activation also causes a shock wave that damages the Lewis and Clark, forcing the entire crew to board the Event Horizon. After Justin is pulled out, he is in a catatonic state, terrified by what he saw on the other side. He attempts suicide, forcing the crew to place him in stasis.
