(CNN) -- The family of a Florida teen who died after being Tasered by police wants answers from authorities in Miami Beach.

Miami Beach police said officers spotted aspiring artist Israel Hernandez spray-painting the side of a vacant McDonald's off Collins Avenue, the city's main drag. Hernandez led them on a foot chase, ignoring commands to stop, until he was cornered, they said.

"In order to affect his arrest, an officer deployed his conducted electrical weapon (TASER)," police said in a prepared statement. But afterward, Hernandez "displayed signs of medical duress" and was taken to a nearby hospital, where he was pronounced dead around 6 a.m. Tuesday.
