In a recent presentation at Victory Bible Church, Acting Captain Ethan Marquez of the Altadena Sheriff’s Station outlined critical steps residents must take to protect their properties amid rising concerns about looting and squatting during ongoing post-disaster recovery efforts.

Captain Marquez emphasized that the Sheriff’s Department has quadrupled its staffing in the Altadena area in response to increased criminal activity, especially targeting sites with rebuilding materials valued in the billions. The heightened law enforcement presence is aimed at curbing theft and unauthorized occupation of vacant properties.
A central focus of the talk was the importance of a “letter of agency”, a form property owners must complete and file at the Sheriff’s Station (780 E. Altadena Drive). This document authorizes deputies to act on behalf of property owners to remove trespassers, providing the legal standing necessary for swift enforcement.
Marquez made it clear that digital surveillance alone is not sufficient. “Fencing and clearly visible ‘No Trespassing’ signs are essential,” he said. “No fence is foolproof, security needs layers.” According to the Sheriff’s Department, these physical deterrents, combined with a signed letter of agency, significantly increase law enforcement’s ability to intervene.
The community was reminded that Altadena chose to remain open after recent natural disasters to expedite debris removal and prevent an economic slowdown, a move that, while beneficial, also left properties more vulnerable to opportunistic crimes.
