The 29 Palms Marine Base was placed into a lockdown today after an unconfirmed report of shots fired. Base Public Affairs Officer Capt. Zachary Colvin told Z107-7 News at about 9:00 Monday morning, the base Provost Marshall’s office received an anonymous report of shots fired. Out of an abundance of caution the base was locked down until investigators could verify the report. The subsequent investigation revealed the gunshot heard was an “Inadvertent discharge” and no one was injured in the incident. At about 12:20 p.m. the Provost Marshall’s office lifted the lockdown.
