Monster & brother burying their mom

This is the Florida school shooter and his younger halfbrother interring their mother’s ashes last year.

Accused mass murderer Nikolas Cruz, 19 (right) is pictured alongside Zachary, 18, who was involuntarily committed to a mental facility last Friday, according to a source who provided the snapshot.

The brothers are holding an urn containing the remains of their mother, Lynda Cruz, who died on Nov. 1 due to complications from the flu, according to the tipster, who was friends with Lynda and the boys’ caretaker, Roxanne Deschamps.

Lynda and her husband, Roger, adopted the kids as infants.

Roger died of a heart condition in 2004.

Only Lynda and Roger knew who the boys’ birth parents were, but Lynda said the boys’ biological mother was a “drug addict,” according to the source.

The brothers stand to inherit an unknown sum of cash from their parents’ estate — Nikolas told a family he was staying with he was set to inherit $800,000, and court documents indicate the estate was worth about $1 million, but the re- cords do not factor in Lynda’s outstanding debts, which would have to be paid by the estate.

Deschamps filed a court petition to be put in charge of settling Lynda’s estate the day after the Feb. 14 shooting, when Nikolas allegedly killed 17 of his former classmates and teachers at Marjory Stoneman Douglas HS in Parkland, Fla.
