A ruthless parolee accused of killing popular sneaker reseller “Upscale Cracc’’ in SoHo in June was just nailed partly by his own black and yellow kicks, new court papers revealed.

Jayquan Straker, 35, had been sprung from prison in September after serving 10 years for a 2013 home-invasion burglary in Canarsie, Brooklyn — in which he and a cohort dressed as FedEx men to barge in and force the family to the floor at gunpoint, including a 10-year-old and a 6-year-old.

The suspect was still on parole when he was then arrested for alleged illegal gun possession within three months after his release, law-enforcement sources said.

The disposition of Straker’s weapons case is unclear — its records are sealed, according to the Brooklyn District Attorney’s Office.

But Straker was back on the streets June 25 — when he and an accomplice allegedly killed Javier Osorio-Mejia, 31, an entrepreneur described online as “a mainstay at sneaker releases in New York City for years.’’

Straker, of upstate Poughkeepsie, was tied to the chilling slaying with the help of video from the Manhattan murder scene and his own phone — both of which showed him wearing the easily identifiable sneakers, court documents say.

Cops “viewed videos contained in the content of the iCloud of the defendant wearing black and yellow sneakers that are consistent with the black and yellow sneakers worn by the individual that fired the firearm at 40 Greene Street,’’ the criminal complaint says.

Straker was nabbed Saturday, charged with Osorio-Mejia’s murder and held without bail.

His alleged accomplice is still in the wind.

The suspects allegedly staked out their victim at a strip joint, Dream Gentleman’s Club, in Queens and then followed him when Osorio-Mejia left with a woman in his white Land Rover.

Osorio-Mejia pulled over in SoHo and got out of the pricey car to use the bathroom, and that’s when he was jumped by the robbers, authorities say.

Straker is accused of whipping out a gun and shooting him — then joining his fiendish pal in robbing the victim’s limp body, including of a Rolex.

Osorio-Mejia is believed to have been targeted over the flashy jewelry he wore in online photos.
