A man found fatally shot in an alley in Southeast Washington on Wednesday, his wrists bound with plastic zip ties, had been kidnapped and was shot after his family dropped off ransom money, according to documents filed in federal court Thursday.

Authorities arrested a suspect in the kidnapping but have not filed charges in connection with the killing. The victim was identified as Andre Simmons Jr., 28, of Bowie, Md. Attempts to reach his family were not successful.

Police in Prince George’s County and in the District have said little about the shooting and kidnapping. They declined to comment Thursday beyond a brief statement noting the fatal shooting, which occurred about 6:25 a.m. in the 600 block of Atlantic Street SE.

Additional information was contained in documents filed in U.S. District Court charging Darin C. Moore Jr., 25, of Bowie with kidnapping and using a firearm in a crime of violence. Magistrate Judge Robin M. Meriweather ordered Moore detained until a detention hearing Tuesday.

The victim and suspect have extensive arrest records in Prince George’s County. Moore is on probation from a gun and conspiracy conviction stemming from a killing during a botched drug deal in 2015 in Bowie, court records show. He was acquitted of first-degree murder. Simmons had been scheduled to be sentenced June 28 in a drug case in Prince George’s County.

Authorities declined to say whether there was a connection in any of the criminal cases involving the men. Attorneys in their Maryland cases could not be reached.

The court document says Simmons was kidnapped Tuesday night near his residence in Bowie when a dark-colored Nissan Maxima struck him as he drove a moped. Two men with guns forced him into the vehicle, bound his hands and drove off, the document says. Authorities said “the kidnappers made several calls to a family members of Simmons, demanding ransom money in return for Simmons’ safe release.”

About 4:50 a.m. Wednesday, the court document says, a relative dropped $7,000 at a location along Benning Road in Northeast Washington. Occupants of a black Acura were seen collecting the money, the document says. The car then sped away.

Police said that at 6:23 a.m., ShotSpotter, a device that detects gunshots, reported that 19 rounds had been fired in an alley off Atlantic Street, seven miles from the money drop location. Police reported finding Simmons dead.

In May, police had hidden a GPS tracking device on a Nissan believed to have been used in a robbery. Authorities said that the vehicle description was similar to that of the Nissan used in the kidnapping, prompting them to review the tracking data.

The court document says they learned the same Nissan, registered to Moore, was at the site of the abduction and the killing.

Authorities said they found the car at a house in Capitol Heights shortly after the killing and that Moore surrendered after a standoff.
