#Double-slay suspect once beat murder charges related to Stephon Marbury’s cousin

The violent ex-con wanted in the recent assault-rifle murders of a man and woman in Brooklyn once beat the top charges in a 2004 double-slaying in which the cousin of former Knicks star Stephon Marbury was killed, The Post has learned.

Disguised in a blue trench coat and a blonde wig, Charles Hernandez allegedly sprayed dozens of rounds with an AR-15-style rifle in broad daylight Saturday afternoon, gunning down Chioke Thompson, 23, and Stephanie Perkins, 39, on an East New York stoop, cops said.

Hernandez, 47, was paroled in 2018 after getting locked up on a gun-possession conviction stemming from another incident of gunplay that left two people dead, according to court records and law-enforcement sources.

After heated words were exchanged at a Sept. 2004 birthday party in NYCHA’s Coney Island Houses, Hernandez and at least three other men took it outside, according to sources and reports from the time.

Among the men were Allen Lewis, 20, and Yusef McEaddy, 32, a cousin of former All-Star point guard Marbury and, according to sources, a friend of Hernandez.

As tensions escalated, guns were drawn, Lewis fatally shot McEaddy and Hernandez in turn gunned down Lewis, according to sources, who described the clash as gang-related.

“I am hurting. This life is a living hell,” said Renee Ealey, Lewis’ aunt, at the time. “He was a good kid.

“I hope the guy who killed him rots in hell.”

Hernandez — on parole at the time after a first-degree assault conviction — was initially arrested and charged only with Lewis’ murder, but prosecutors tried to pin McEaddy’s death on him as well on the premise that Hernandez drew his weapon first, triggering the deadly chain of events, sources said.

The argument didn’t fly in court, however, with a jury acquitting Hernandez in both deaths during his 2006 trial, sources said.

He was instead found guilty on two counts of weapons-possession, and sentenced to 12 to 15 years behind bars, according to court records.

It remains unclear what prompted Hernandez to allegedly gun down Thompson and Perkins, who died in each other’s arms on Van Siclen Avenue near Livonia Avenue.

Hernandez, who is also identified as Charles Joy in state corrections records, is known to drive a blue 2007 Chevrolet CBT with New York plates, according to police.

He is described as armed and dangerous.
