The second suspect in custody for an Aug. 30 kidnapping and double homicide has waived extradition and should be returned to Atlanta later today, Atlanta police confirmed.

Richard Augusta “Fathead” Wilson, 41, was arrested Thursday morning while trying to pawn an AK-47 rifle and two other guns at Quick Pawn in Birmingham.

He was arrested after the pawn shop’s clerk notified police when he appeared nervous and lacked ID, according to previous reports.

His alleged partner, Andre Cleveland Gay, 40, was arrested Sept. 25 on multiple counts of kidnapping, murder, felony murder, aggravated assault with intent to commit murder and possession of a firearm by a convicted felon, jail records show. He is being held without bond.

“These are very violent offenders,” Capt. Paul Guerrucci, head of the Atlanta Police Department’s homicide unit, told reporters Thursday.

Gay and Wilson are accused of kidnapping for ransom Jeronta Brown, 23, and his pregnant girlfriend, Briana Brooks, 21, just steps from the door to their Colleen Court home in DeKalb County on Aug. 30. The two were found shot on Ridge Avenue in northwest Atlanta, 17 miles from where they had been taken. Brown was already dead. Brooks died several days later when she was taken off life support after delivering their second child prematurely.

Even with two men suspected of kidnapping and killing a young DeKalb County couple in custody, police are still looking for people who might have helped them.

“We know that there are those in the community who assisted in harboring this dangerous fugitive over the last few weeks,” Keith Booker of the U.S. Marshal’s Service said in a news release. “We know who you are, and will be coming to arrest you in the near future.”

.Gay was paroled in January after spending 22 years in prison for murdering a woman and a baby. Gay was 15 in November 1990 when he shot through the door of an apartment in the McDaniel-Glenn housing project in southwest Atlanta, killing 39-year-old Cathy Dozier and 18-month-old Michael Broughton.

And Wilson was indicted earlier this year on charges he murdered Fikree Muhsin Jordan on Jan. 9. The 37-year-old Jordan was found shot to death in the middle of Farrington Place in southeast Atlanta.
