Andrew McGann had been put on administrative leave by a Texas school district in 2023 for improper classroom management.

Andrew James McGann, 28 — who authorities say admitted to butchering Clinton David Brink, 43, and wife Cristen Amanda Brink, 41 Saturday — was strange and standoffish in class, said Sierra Marcum, whose son was in McGann’s fourth-grade class.

Police had been searching for McGann since July 26, when they say he fatally stabbed Clinton David Brink, 43, and Cristen Amanda Brink, 41, while they were hiking in Devil's Den State Park with their two daughters, aged 7 and 9. The children weren't hurt and are safe with family members, according to police.
