Rapper POORSTACY Dead at 26

Rapper POORSTACY is dead ... and it sounds like he may have taken his own life.

The death of POORSTACY -- legal name Carlito Milfort -- was confirmed by the Palm Beach County Medical Examiner ... the Boca Raton Police Dept. told TMZ he died early Saturday in the city.

A Boca Raton hotel worker tells TMZ ... POORSTACY was transported to a local hospital for a medical emergency Saturday morning ... he was the only one hospitalized. We're told the rapper had been staying for 10 days at the hotel ... he had checked in with a woman and a toddler. No one else was reported injured Saturday.

The cause of death is unclear -- we're working on it -- but folks leaving comments on POORSTACY's most recent Instagram post are indicating they are under the belief he may have died by suicide.

POORSTACY was an up-and-coming artist from Palm Beach who blended different genres like emo rap, punk rock, and punk rap.

His biggest accomplishments had been a feature on the "Bill & Ted Face the Music" movie soundtrack, which earned a Grammy nomination ... plus a handful of collabs with Travis Barker.

POORSTACY and Travis actually worked together on three songs ... and the biggest one is called "Choose Life."

POORSTACY was only 26.

RIP
