A 48-year-old Connecticut drug kingpin who killed a mother and her 8-year-old son so she wouldn’t testify against his brother has received clemency as part of former President Joe Biden’s clemency for nearly 2,500 federal inmates he described as “non-violent.”

Adrian Peeler, a Bridgeport drug trafficker, killed a woman named Karen Clarke and her 8-year-old son just weeks before they were supposed to testify against his brother, who was accused of shooting Clarke’s boyfriend in front of the child.

The mother and son were ambushed as they returned home to their apartment in January 1999. Police found the boy with a bullet hole in the back of his head on the stairs and Clarke riddled with gunshot wounds and her outstretched hand inches from a phone, according to CT Post.

Peeler’s brother, Russell Peeler, was sentenced to death for ordering the murders but had his punishment commuted to life in prison without parole after Connecticut abolished capital punishment.

The list of Biden’s “non-violent” clemency recipients, released separately, included more violent offenders than just Peeler.

Two Virginia men serving life prison sentences in connection with a drug case that left a Sussex County police officer dead in 1998 were also set free.

Ferrone Claiborne and Terence Richardson, known as the “Waverly Two,” both admitted to playing a role in the death of Officer Allen Gibson but were later acquitted of murder at trial due to an apparent lack of evidence. But they were convicted of lesser charges and sentenced to life in prison anyway.

Gibson, 25, stumbled upon a back alley drug deal in Waverly involving Richardson and Claiborne. According to authorities, the two attacked and disarmed him. He was later found with a gunshot wound to his stomach, right below his bulletproof vest.

Richardson pleaded guilty to state charges for involuntary manslaughter and Claiborne pleaded guilty to being an accessory after the fact. They later went to trial in federal court, where prosecutors failed to convince the jury they were guilty of murder but secured convictions on drug trafficking charges.

“I am absolutely outraged by what has happened,” Crissana Gibson, the slain officer’s daughter, said in a statement released by Virginia Attorney General Jason Miyares. “My heart is shattered knowing that the men that killed my father are going to be released from prison and can walk the streets freely.”

Separate from the “non-violent” commutations, Biden ignored pleas from former FBI Director Christopher Wray and ordered the release of Leonard Peltier, a left-wing activist convicted for his role in an ambush shooting that left two FBI agents dead in South Dakota in 1975.

On his last day in office, he commuted Peltier’s life prison sentence and gave last-minute preemptive pardons to his family members and allies, including his siblings, Dr. Anthony Fauci, Mark Milley and members of the January 6 Committee. He had previously pardoned his son, Hunter.
