A lawsuit alleges a grandmother 'froze to death' after being locked outside a Colorado assisted living facilityThe woman, 97, was seen in surveillance footage banging on a door before, it's alleged, she "froze to death." The woman's family is suing the facility for wrongful death. The grandmother was captured on surveillance footage "banging on the glass panes of the French doors located directly adjacent to the nurses' station for help," according to the wrongful death lawsuit seen by Fox News. Staub, who her family described as a "beloved mother and grandmother," was locked outside wearing "only pajamas, a robe, boots, and gloves," the lawsuit said. "Where we found deficiencies, we required the facility to quickly make changes and closely monitored the facility until it completed all corrective actions."
