Federal authorities on Wednesday showed off results of Southern California raids early this month that led to the biggest domestic seizure of methamphetamine in U.S. Drug Enforcement Administration history.

The 2,224 pounds (1,008.7 kilograms) of methamphetamine was seized Oct. 2 during an investigation of a drug-trafficking organization with ties to the Sinaloa cartel, the DEA said in a statement.

The investigation led to search warrants being served at narcotics stash houses in the Riverside County cities of Moreno Valley and Perris, east of Los Angeles.

Also seized were 893 pounds (405 kilograms) of cocaine and 13 pounds (5.9 kilograms) of heroin.

DEA Acting Administrator Timothy J. Shea and other law enforcement officials displayed the evidence during a press conference at a DEA warehouse in Montebello.

“The largest DEA domestic seizure of methamphetamine in history is a significant blow to the cartels, but more importantly it is a gigantic victory for communities throughout Southern California and the United States who have had to deal with the torrent of methamphetamine coming into their neighborhoods,” Shea said.
