possible? 18-year-old Boy Rapes 82-year old Woman for 4hours.

Asa Robert, 18, allegedly raped an 82-year-old woman in her Brooklyn home.

A sadistic sexual predator raped and sodomized a gutsy 82-year-old woman whose motherly chat about family and food failed to soothe the monster during a night of terror.

The 4 1/2-hour ordeal ended around 6:30 a.m. Monday when the brute, 18-year-old Asa Robert, slammed the octogenarian against a wall, threw her on a bed in her Brooklyn home and sexually assaulted her, police said.

Local fruit shop employee Mark Andrew, 38, identified the face on a wanted poster as a neighborhood panhandler.

“They should hang him here, here in the middle of Brighton Beach,” Andrew said. “How can you do something like this? Terrible. This is not human.”

The nightmare started shortly after the woman spied the knife-wielding intruder kneeling in the darkness of her bedroom around 1:45 a.m., cops said.

A police source said the Brighton Beach woman, who suffers from obsessive compulsive disorder, left the door open when she went to do some late-night sweeping outside the home. That's when Robert slipped past her and into the house, police said.
