The younger brother of deranged school shooter Nikolas Cruz was committed to a mental health facility, according to reports.

Authorities removed someone Friday from the home of Rocxanne Deschamps, a longtime family friend of the Cruz brothers who took them in after their adoptive mother died of pneumonia in November, The Palm Beach Post reported.

A friend of Deschamps confirmed Zachary Cruz, who turns 18 next week, was the person removed from the home.

The younger Cruz brother was involuntarily committed under Florida’s Baker Act, under which he can be held involuntarily for up to 72 hours for an involuntary psychiatric exam. It’s unclear if he’s been released.

Nikolas Cruz left Deschamps’ Lantana, FL mobile home around Thanksgiving after he and Deschamps squared off over a gun.

“He bought a gun and wanted to bring it into my house,” she said in comments that have since been wiped from her Facebook page, the paper reported.

Chad Bennett, a family friend, said Deschamps gave Cruz an ultimatum and Cruz “chose the gun and he left.” He moved in with family in northern Broward county, a Cruz family lawyer told the newspaper.

The Palm Beach Post said it was not known if the gun Cruz brought to the Deschamps home was the AR-15 semi-automatic rifle Cruz used to kill 17 people in Wednesday’s mass shooting at Stoneman Douglas High School in Parkland, FL.
