U.S. Navy officials said a Virginia Beach, Va.-based special forces service member was killed Wednesday during a parachute jump in Casa Grande.
Authorities said the victim, a Navy SEAL whose name was not released, died after plunging to the ground near one of the holes at the Mission Royale Golf Club.
Golf course representatives declined to comment about the incident and referred all calls to local authorities.
Casa Grande police Cmdr. Scott Sjerven said the death came during a SEAL training exercise.
The military is handling the investigation into the death, which occurred about 7 a.m., he said.
Navy spokesman Lt. David Luckett said it would be at least 24 hours before the SEAL's name would be released, pending notification of next of kin.
Luckett said the victim's military job designation was as a special warfare operator assigned to the East Coast unit. He said the incident is under investigation.
Phoenix television station KSAZ-TV (Channel 10) reported the victim was from Virginia and had been participatingin a training exercise based in the Marana area, north of Tucson.
The Navy's SEAL force, standing for Sea, Air, Land, was first commissioned by the maritime service in 1962.
