A domestic dispute in Port Saint Lucie turned deadly on the morning of February 18, 2026, when 69-year-old Glen Morrison was shot and killed at his home on Northwest Ketona Circle. Police were called about 7:45 a.m. and found Morrison inside the residence with a fatal gunshot wound; investigators say the shooting took place in the garage after an argument with his son.

Authorities identified 41-year-old Sheldon Brian Morrison as the primary suspect. The victim’s wife was at the home and is believed to have called 911. A lockdown was briefly imposed at nearby Somerset College Preparatory Academy during the search.

Law enforcement located and arrested Sheldon Morrison in Hollywood, Florida, at about 1:30 p.m. the same day; he was taken into custody without incident. Neighbors said there had been no prior police calls for the residence and suggested the family was considered nice; reports indicate the dispute may have been over a family pet.

Did anyone in the Port Saint Lucie area see the Cadillac or have information about tensions in the household before February 18?
