Isai Cadalzo, 22, was shot and killed in Metairie, Louisiana, in June 2019 as he was on his way home from work. Cadalzo had moved to the area from Honduras; family described him as kind and devout, a guitar player at his church who helped others, including the homeless. His death was one of a string of apparently random shootings carried out over the same period.

Authorities later identified 22-year-old Sean Barrette as the shooter; his attacks that week also killed Nicky Robeau, 57, and Manuel Caronia, 45, and were connected to another homicide earlier that month in New Orleans East. The arrest of Barrette followed the killings and revealed a history of mental health issues. The victims families were left reeling and struggling to make sense of the sudden violence.

Did anyone who knew Isai, where he worked, or his routines in Metairie come forward with information about that day?
