Two suspects have been arrested and charged with murder in the death of a Virginia man who scammed banks out of more than $50 million and later testified as a jailhouse informant in a capital murder case.

Prince George's County Police said robbery was the motive in the slaying of Osama El-Atari, 37, of Leesburg. El-Atari was reported missing in Loudoun County, Virginia, last week and found shot dead inside a pickup truck in Upper Marlboro, Maryland, on Saturday.

Two men, 29-year-old Eric Garris of Waldorf and 26-year-old Taqwa Muhammad of Lusby, have each been charged with murder and were being held without bond Thursday.

Police gave no indication that El-Atari's death was related to his testimony as a jailhouse informant.
