Police are searching for an alleged coward who they say has been robbing elderly women in Brooklyn and Queens. The suspected weasel previously struck on March 2nd at around 1 p.m., following a 91-year-old woman into her Park Slope brownstone, choking her, flashing a gun, then pushing her into the foyer and demanding cash. The victim, Elizabeth Gioino, told CBS2, "I said, 'Please leave me alone! I’m a sick woman! I’m old enough! Leave me alone!'"

Around that time, cops say a 50-year-old man encountered the pair, and the robber pointed his gun at him and took his money, too, making off with $370 altogether.

Cops say the serial home invader has attacked four other times, most recently on Saturday in Kensington. He allegedly followed an 83-year-old woman into her building near Ocean Parkway and Beverly Road and, waiting until she entered her apartment, knocked on her door. When she answered, he hit her in the face with a hard object, but did not take anything, according to the NYPD.

Each of the other three instances follow a similar pattern, though he usually took cash. In one case, he allegedly tried to tie up his 71-year-old victim in her Park Slope home, and in another he followed a 43-year-old man into his home in Prospect Heights, and once inside, robbed him and an 81-year-old woman who was there at the time. The brutal robberies date back to January 20th, and also took place in Ridgewood, Queens.

Police describe the suspect as 40-60 years old and standing 5-foot-10. He was last spotted wearing a black jacket. He appears to have white hair.
