Late Jackson 5 member Tito Jackson suffered a medical emergency in New Mexico prior to his death.

An officer from the Gallup Police Department was "alerted to an individual requiring medical attention" on Sunday evening, according to a Monday press release from GPD. The officer subsequently requested an ambulance for the individual, who was later identified as Jackson.

Jackson was then transferred to a local hospital, where he was pronounced dead upon arrival. Details on Jackson's condition leading up to his hospitalization were not disclosed.

"This information is derived from a preliminary investigation that is still ongoing," the release states. "Investigators are actively interviewing witnesses and examining both physical and electronic records. The department's understanding of the facts and circumstances may evolve as additional evidence is gathered and analyzed."
