AMERICAN HORROR STORY: CCTV Captures The Moment A 4 Year Old Was Abducted From His Room, Stabbed To Death A Day Later

The man suspected of abducting four-year-old Cash Gernon before stabbing him to death and dumping his body on a street in Dallas allegedly returned hours later at daybreak to snatch his twin brother Carter.

The chilling moment Darriynn Brown hovers menacingly over the crib of Carter Gernon, as Cash lay stabbed to death on a street a half-mile away, is captured on home surveillance footage.

Brown, 18, reaches down and touches the boy as he stirs in his toddler bed, before wandering around the room, seemingly disturbed by a sound, and fleeing the room, leaving the boy sleeping peacefully.

A few hours earlier just before 5am, Brown allegedly broke into the same home and made off with Cash, who was later found dead, shirtless and barefoot about eight blocks away on the 7500 block of Saddleridge Drive.

On Tuesday, the Dallas Medical Examiner revealed Cash had died of multiple stab wounds. Police had earlier said his wounds appear to have been inflicted by an 'edged weapon.'

The two brothers had been staying at the home located on the 7500 block of Florina Parkway where they shared a bedroom located in the back of the house.

In night-vision footage, Brown creeps in dressed in a hoodie, backpack, sweatpants, and sneakers, and hovers menacingly over the two boys.

Roughly an hour and 45 minutes later, Cash was found lying dead in a pool of blood in a quiet residential Dallas street after being stabbed with what police described as an 'edged weapon.'

Sherrod revealed Brown was known to the family as the brother of her older sons' friend, but said she does not know why he would've targeted the toddlers.
