The perturbed pair who took in Florida school shooter Nikolas Cruz back in November have opened up about living with the teen and say they didn't see the danger he posed.
Kimberly, 49, a neonatal intensive care nurse, and James Snead, 48, a military intelligence analyst, agreed to allow the 19-year-old live in their Parkland home after their son, a friend to Cruz, inquired.
Cruz's new home at the Snead residence came just days after his adoptive mother, Lynda Cruz, passed away from pneumonia on November 1, according to the Daily Mail.
The Snead couple have now revealed that they failed to see the dark side of Cruz, who gunned down 17 innocent individuals in a Valentine's Day rage.
While speaking with the South Florida Sun Sentinel, a wearied Kimberly said: "We had this monster living under our roof and we didn't know."
Her husband, James, also added: "Everything everybody seems to know, we didn't know... It's as simple as that."
The couple told the local newspaper in a sit-down interview they knew Cruz had been "extremely depressed" after the death of his last living guardian, Lynda.
They said he was noticeably "immature" but seemed to be "growing happier" after moving into a new home.
Cruz had unusual eating habits and at times would place cookies inside steak and cheese sandwiches.
The family, who had pets in their home, claimed there were no signs of animal cruelty, despite several claims by neighbours who revealed disturbing details about Cruz's treatment of animals.
The couple admitted they allowed the "gun-obsessed" teen to keep an AR-15 rifle in their home, however, as they are avid about gun safety, they made him buy a locking safe to keep in his bedroom.
Inside the safe, were other various guns as well as knives. The pair instructed Cruz to ask for permission before unlocking the safe - which they claimed to the Sentinel he did twice since moving in.
Kimberly reportedly encouraged Cruz to attend therapy sessions after the passing of his adoptive mother.
She said just five days before the shooting, she and Cruz attended a session together.
Still, the couple claims the night prior to the Valentine's Day shooting, there was no indication the teen had any unusual behaviour.
The parents reportedly asked Cruz if he needed a ride to school the morning of February 14, when he declined and said he didn't even need to go.
"It's Valentine's Day and I don't go to school on Valentine's Day," he said, the couple told the Sentinel.
The Sneads recalled receiving the "panic-stricken" phone call from Cruz around 2.30pm that day.
Cruz informed them about a shooting at Marjory Stoneman Douglas High - when James told him to walk to the nearby Walmart and that he was on his way to pick him up.
During the drive, James received a troubling phone call from a SWAT officer inquiring about Cruz's whereabouts.
That's when James realised there were more troubling details to the story.
James phoned the officer back and ordered police to rush to their Parkland home to check on his wife.
"I need a police presence at my house. Go make sure my wife is OK," James urged in the phone call.
"I was fearing for her life," he recalled in the interview.
Shortly after, Kimberly answered the door, when officers ordered her to put her "hands up".
Police raided the home while Kimberly feared the worst.
Cruz was taken into custody by the time Kimberly and James saw him for the first time since the massacre.
James told the Sentinel that he was forced to hold Kimberly back when she attempted to charge after Cruz while in custody. In a panic, Kimberly then told Cruz: "Really, Nik? Really?"
James added: "He said he was sorry... he apologised. He looked lost, absolutely lost.
"That was the last time we saw him."
Despite the couple's claims they didn't notice his disturbing behaviour, the teen was expelled from school last year, while neighbours and friends revealed details of his love for violence and weapons.
Police had been called to Cruz's homes as many as 39 times over the course of seven years over reports of violence or suspicious behaviour.
