The Florida family housing alleged school shooter Nikolas Cruz say they didn’t realize the troubled teen had a key to the gun safe holding his firearms.

“Before he moved in, one of the stipulations was he had to get a gun safe,” James Snead, whose family took in Cruz after his mom died, told “Good Morning America” on Monday.

“I thought I had the only key.”

Snead — whose 17-year-old son went to school with Cruz and was on campus when the 19-year-old allegedly opened fire with an AR-15 rifle last week, killing 17 people — said their houseguest had only twice asked to access the safe.

Snead and his wife, Kimberly, said they were fine with him having guns “because he followed the rules.”

“They were not allowed to be out if we were not home. If one of us wasn’t home, he knew that. To our knowledge, he never had them out,” she said.

The claim stands in contrast to statements from the family’s lawyer, who had previously been speaking on the Sneads’ behalf and told the Sun Sentinel last week: “The family made him keep it in a locked gun cabinet in the house but he had a key.”

The Sneads have maintained that they didn’t notice anything off about Cruz.

“He was very polite. He seemed normal,” James Snead told “Good Morning America.”
