“What keeps me alive is putting out these posters and talking to people,” Hart said. “That’s what keeps me going.” She spent Christmas Eve issuing a renewed plea for the public to keep their eyes peeled for Sean, who had been living in Seven Oaks Tertiary Mental Health Facility on Blenkinsop Road for about five years. Sean, who has been diagnosed with schizophrenia, had left the facility twice before, but he always returned on his own or had been found within six days, she said. Hart has created a new poster with photos and a description of Sean, as well as stock images of the shoes and coat he was last seen wearing. He may have taken off his black Under Armour hiking boots, so Hart is asking people to look for the boots as well as Sean.
