An arrest has been made in connection with the shooting death of an elderly Queens woman.

Police have charged 22-year-old Julian Douglas of Queens with second degree murder in the death of  Leta Webb last month.

Douglas also faces a weapons possession charge.

Investigators say they were lead to Douglas through a tip.

The 70-year-old Webb was shot in the head and arm when she answered the door of her South Jamaica home on March 31.  

Officials say that there is no known motive at this time—although police were investigating the possibility that the shooting may have been done in retaliation.

Webb's daughter says her adopted brother is in prison for murder.
