New York City police are urging residents to be on alert for a man suspected of torturing an elderly Queens couple for hours before killing them and setting their home on fire – all under the guise of needing to come inside to charge his phone. 

The NYPD has released new photos of 42-year-old Jamel McGriff, an ex-con with a decades-long rap sheet, as police warn he is considered armed and dangerous. 

The victims have been identified as Frank and Maureen Olton, 76 and 77.

McGriff has a lengthy criminal history spanning decades, including a 16-year-long prison sentence stemming from a 2006 robbery conviction in which he was out on parole, FOX 5 reported. He is also wanted for two recent robberies – one at a Harlem GameStop in July and another at a Manhattan Verizon store, where he was reportedly fought off by a store clerk who noticed he was carrying a fake gun, police said. 

Last year, McGriff also failed to register as a sex offender, a parole violation, police said. 

McGriff was last spotted pawning two cellphones in the Bronx on Tuesday, police said. He was also seen on surveillance video walking down a sidewalk in Queens wearing a black hat, black jacket, blue jeans and black sneakers while carrying a backpack and paper bag. 

Anyone with information is asked to call the NYPD’s Crime Stoppers Hotline at 1-800-577-TIPS, share tips online at https://crimestoppers.nypdonline.org or on X @NYPDTips.
