() Multiple suspected gang members are behind bars after the bust of a drug trafficking scheme using the U.S. mail, a taco truck and homes in the Houston area, Immigration and Customs Enforcement announced.

In an unsealed 29-count indictment, the Justice Department alleges a group of at least 15 people imported methamphetamine from Mexico to the U.S. and then distributed it along with other drugs like crack cocaine, heroin, oxycodone, psilocybin mushrooms and more.

“Several of the defendants are also alleged to have used firearms in furtherance of their narcotics trafficking and illegally possessed firearms despite having previously been convicted of felonies,” said Matthew R. Galeotti, head of the Justice Department’s Criminal Division, in a statement.

Those charged include:

• James Michael Brewer aka “Creeper,” 33
• Jonathan Alvarado aka “Joker,” 28
• Alexis Delgado aka “Chino,” 28
• Hector Luis Lopez aka “Capulito,” 23
• Kylie Rae Alvarado, 24
• Ruby Mata, 31
• Victor Norris Ellison, 35
• Mexi Dyan Garcia aka “Mexi,” 31
• Jesus Gomez-Rodriguez aka “Jr.,” 33
• Enzo Xavier Dominguez aka “Smiley,” 32
• William Alexander Lazo aka “Miclo,” 21
• Alfredo Gomez aka “Fredo,” 26

Three people accused of participating in the drug trafficking scheme remain at large.

Warrants are currently out for the arrest of:

• Jose Francisco Garcia-Martinez aka “Paco,” 29
• Guatemalan national Marcos Rene Simaj-Guch aka “Taco Man,” 41
• Jose Eduardo Morales aka “Primo,” 22

The ICE investigation, conducted alongside Houston police and other federal agencies, could see nearly all suspects serving a life sentence if convicted.
