A 22-year-old man has been charged in the murder of beloved 70-year-old Queens grandmother Leta Webb, who was fatally shot in the head  in the doorway of her South Jamaica home.

Julian Douglas, 22, of 131 street in Queens was charged with second degree murder and criminal possession of a weapon.

The NYPD says that on  Tuesday, March 31, at around 1:30 a.m., Douglas  shot Webb dead when she opened her door of her home at 152-22 119 Avenue.

A  video surveillance camera caught images of a white Ford Econoline Van that Douglas reportedly used in his getaway.

Cops released little additional info other than reporting the break in the case on Saturday.

Webb’s family and NYPD Chief of Detectives Robert Boyce, who described Webb as a "stand-up citizen," the shooting may have been a “possible retaliation” against another family member, reports DNAinfo.

Webb’s son, Arnold Webb, 27, is serving 25 years in prison after pleading guilty to gang-related  first-degree manslaughter in 2011, DNA says.
