Frank Contreras aka TANK

Frank Contreras, 19, a former Miami Beach High student, was charged with first-degree felony murder Thursday. Detectives had arrested Charles J. Greenfield, 33, on the same charge late Wednesday.
Investigators say the pair provided heroin to Mark S. Harris, 21, who was found dead of an overdose on Jan. 24 in his truck in a municipal parking lot off 41st Street and Prairie Avenue.
Greenfield told Miami Beach Detective Wayne Holbrook that Harris was his pot-and-cocaine buddy.
According to an arrest report, Harris went to Greenfield's mid-Beach apartment Jan. 23 and paid Greenfield $60.
Greenfield called Contreras, who dropped by and gave them baggies of heroin and cocaine. Brokering the heroin deal netted Greenfield $10, police said.
Harris walked out, injected himself in the truck and died, police said.
By law, someone who commits certain felonies -- in this case, selling drugs -- can be charged with felony murder if someone dies in the process.
In November, Miami Beach police arrested Christopher Rodriguez, 22, a security guard, after he allegedly sold Ecstasy pills to a 15-year-old on her way to party in South Beach. The teen was hospitalized and died. Rodriguez, who told police he had just started selling drugs, is awaiting trial on charges of first-degree felony murder and selling a controlled substance.
In February 2007, Miami-Dade police charged Melanie Mazzotti, 30, with first-degree murder in the death of jailed boyfriend Edward Hawkins, 26. Police alleged she smuggled drugs in a package that he then swallowed to conceal from corrections officers.
The package later burst in his stomach and killed him.
