SEATTLE, WA (KTLA) -- A Los Angeles man is one of two suspects accused in a plot to use machine guns and grenades in an attack on a military recruiting station in Seattle that also houses a daycare, the U.S. Justice Department said Thursday.

According to a federal complaint, Abu Khalid Abdul-Latif, aka Joseph Anthony Davis, 33, of Seattle, and Walli Mujahidh, aka Frederick Domingue, Jr., 32, of Los Angeles, took possession of machine guns that they purchased and planned to use in an attack on the Military Entrance Processing Station on East Marginal Way, Seattle.

The MEPS is where each branch of the military screens and processes enlistees. In addition to housing many civilian and military employees, the building houses a federal daycare center.

Agents were tipped off to the plot by someone the men tried to recruit as a participant.

Law enforcement began monitoring Abdul-Latif and Mujahidh, including the weapons transactions.

Agents even disabled the suspect's weapons so they posed no risk to the public.

The defendants initially planned an attack on Joint Base Lewis-McChord, but later changed targets.

Since early June, the conspirators were captured on audio and videotape discussing a violent assault on the Military Entrance Processing Station.

Abdul-Latif and Mujahidh are charged by complaint with conspiracy to murder officers and employees of the United States, conspiracy to use a weapon of mass destruction (grenades), and possession of firearms in furtherance of crimes of violence.

Abdul-Latif is also charged with two counts of illegal possession of firearms.

Both Abdul-Latif and Mujahidh face potential sentences of life in prison if convicted of the charges.
