MS members have been involved in burglaries, auto theft, narcotics, extortion, murder, rape, witness intimidation, illegal firearms sales, car theft and aggravated assaults. In terms of drug trafficking activities, common drugs sold by MS members include cocaine, marijuana, heroin, and methamphetamine.
