The cause of death of Recruit Raheel Siddiqui, 20, of Taylor, Michigan, remains unclear. A spokesman for the depot, Capt. Gregory Carroll, told Military.com that Naval Criminal Investigative Service was investigating the tragedy and the investigation could take three weeks or even longer to complete.
Meanwhile, he said, Siddiqui's unit saw no pause in training.
"The event occurred on training day four and training day six happened today," Carroll said, noting that the recruits had also trained as scheduled on March 19, a Saturday. Sunday is a scheduled rest day from training.
While Carroll said Siddiqui belonged to Recruit Training Regiment, he declined to release his battalion and company.
There was no unit-wide stand-down or discussion following the tragedy, Carroll said.
"The leadership talked to those who needed to be talked to," he said.
Male Marine Corps recruits from the Eastern United States and all female recruits go through Parris Island's 13-week boot camp to become Marines.
Siddiqui arrived at boot camp March 7, 11 days before his death, officials said.
