Updated 3:45 p.m. PST - Naval Medical Center San Diego (NMCSD) operations have lifted the Shelter in Place Order and personnel are permitted to move about the Facility, with the exception of Building 26, where the investigation continues into today's event.

Patient care and access to the NMCSD facility is resuming.

According to initial reports of a single witness, at approximately 8 a.m. this morning three shots were reportedly heard in the basement of Building 26, a combination gym/barracks/administrative facility located on the grounds of the Navy's Medical Center Balboa Park facility.

The ensuing response and investigation by first responders and Navy working dog units, including offices of local federal, state and city authorities, determined that no evidence could be found of shots fired and there were no casualties.

The intensive and thorough search of Building 26, as well as the grounds and additional buildings located on the grounds of NMCSD, did not reveal anything unusual after the initial witness report was made.
