The 19-year-old suspect in the Florida school shooting that killed 17 people didn’t know how to use a microwave, didn’t pick up after himself and didn’t know how to do his own laundry.

The family that took him in following his mother’s death spoke to the Sun Sentinel.

The paper published a story Sunday about the family, who said that what the gunman did baffles them.

They made him buy a locking gun safe to put in his room the day he moved in. He had a handful of guns, including the AR-15 and two other rifles that James Snead said would be considered assault rifles. The gunman, a hunter, also had knives, BB guns and pellet guns.

Snead thought he had the only key to the cabinet but has figured out he must have kept a key for himself. The family kept their own rifles, bought after a burglary a couple of years ago, in a separate locked cabinet.

They told him that he needed to ask permission to take out the guns. He had asked only twice since November. They said “yes” once and “no” once.
