SAN ANTONIO (AP) — Twenty-three suspected members of a Texas prison gang were accused of racketeering in connection with the slayings of 22 people, according to a federal indictment released Wednesday.

The victims were mostly fellow members of the Texas Mexican Mafia or rival gangs. In some cases, they were suspected drug dealers indebted to the gang, which authorities say enforces a street tax on drug dealers who work on gang turf.

The slayings occurred between 2000 and 2005, according to the indictment.
