A US Marine from Sudbury was found dead on a military base near San Diego Monday morning, a spokesman for the First Marine Expeditionary Force said.
Military officials and paramedics found Lance Corporal Michael J. Ronner, 23, at about 9:15 a.m. at Marine Corps Base Camp Pendleton, Second Lieutenant Garth Langley said in a statement.
The paramedics tried to resuscitate Ronner but were unsuccessful, Langley said. The Naval Criminal Investigative Service is investigating Ronner’s death.
A man who answered the phone at Ronner’s Sudbury home Tuesday night and identified himself as the Marine’s father declined to comment.
Ronner graduated from Lincoln-Sudbury Regional High School in 2007, according to Scott Carpenter, superintendent and principal.
Carpenter said Ronner indicated at graduation that he planned to attend Indiana University.
Robert C. Haarde, vice chairman of the Sudbury Board of Selectmen, said in a phone interview Tuesday night that he did not know Ronner personally but that his death is a tragedy for the entire community.
“Our hearts go out to the family,’’ Haarde said.
Langley said Ronner enlisted on Jan. 11, 2010, and was assigned to the Ninth Communication Battalion, First Marine Expeditionary Force Headquarters Group, Camp Pendleton. He was awarded the National Defense Service Medal and the Global War on Terrorism Service Medal.
Ronner had not been deployed overseas since enlisting, according to Langley.
The spokesman declined to say whether Ronner’s death is considered suspicious.
“To preserve the integrity of the investigation process no details are available yet,’’ Langley wrote in an e-mail, adding that the naval investigators will determine the facts of the case.
The investigating agency could not be reached for comment Tuesday night.
