The sister of a Connecticut man who fatally shot his teenage son last week frantically called police to report someone was shot after she called her brother for help with someone trying to break into her house.

Police say Jeffrey Giuliano went outside with a gun at about 1 a.m. on Sept. 27 after his sister called to say someone was trying to break into her house next door in New Fairfield. Authorities say Giuliano saw a person wearing a ski mask holding a shiny object come toward him in a threatening manner and shot him.

He was told later the person he killed was his 15-year-old son, Tyler.

Giuliano's sister, speaking rapidly and trying to catch her breath, says she wasn't sure if her brother was shot. Giuliano's wife also called police.

The 911 calls were released Friday.
