Zachary Humelsine, 25, of Orlando, Florida, was killed on March 2, 2017 in his family home in the Vista Lakes community. Police say his stepfather, Hector Collazo, shot and killed Zachary and Zachary’s mother, 57-year-old Caryn Collazo. Zachary has been described by his family as a gentle giant, a loving son, and a wonderful big brother.

According to police reports, Hector Collazo claimed he was threatened with a knife by Caryn and Zachary. Investigators say Zachary only retrieved a knife after Hector had pushed Caryn to the ground and slammed their bedroom door; when Zachary approached to help his mother, Hector shot Caryn and then shot Zachary multiple times. A 15-year-old son escaped, called 911, and Hector Collazo was arrested at the scene and charged with two counts of second-degree murder with a firearm.

The crime left the family and community reeling. If anyone knew Zachary or has information about the events that night, please come forward.
