A Navy medic shot and wounded two U.S. sailors at a military facility Tuesday, then fled to a nearby Army base, where security forces shot and killed him, claimed police and Navy officials.

The suspect has been identified as Fantahun Girma Woldesenbet, who served as an E-4 Navy hospital corpsman.  He shot and wounded two Navy officers, one critically. The other Navy officer has received minor injuries and is expected to be discharged from the hospital soon.

Despite the severity of the crime, the reason for the 38-year-old man’s shooting at his officers is still unknown. According to the Army Brigadier General Michael J. Talley, an extensive investigation is going on.

It is important to note that the first shooting – where Woldesenbet shot two officers – took place at a military base in Riverside Tech Park. The building serves as the storage facility that is rented by the organization where Woldesenbet worked. Although the exact reasons for the shooting are still unknown, it seems like Woldesenbet had carried out a planned attack.

The local police had been alerted of a shooting incident at around 8:30 am. They claimed that they had responded to an active shooter, at a commercial business center about four miles away from Fort Detrick.

Jeremy Mutschler, director of marketing for Nicolock Paving Stones, has claimed that the shooting incident may have taken place near the company’s Fredrick location, but not at the business itself.

After the first shooting was over Woldesenbet got into his car and drove away to a nearby military base. The officials claimed that he was stopped at the entrance, but he managed to cross the barriers. Just as he was about to take out a gun, the police arrived at the base and shot him dead.
