Victim: Isaiah Furbert, 19.

Date and location of murder: October 18, 2016, Upland Street, Devonshire.

Circumstances: Mr Furbert was fatally shot at 10pm at his mother’s home on Upland Street — the same residence where, nine months later, 20-year-old Jahcari Francis would be shot dead.

Compounding the mystery, Mr Furbert had posted a cryptic Twitter post about death just minutes before he was shot through a bedroom window.

He was pronounced dead at the hospital just a half-hour after posting it.

The teen was the island’s youngest gun fatality in a decade.

His mother told The Royal Gazette in a 2017 interview that Isaiah was with two other boys in his room when three gunshots rang out.

She said her son was well-liked, but that family ties with the St Monica’s neighbourhood might have sparked animosity.
