A Topeka woman has been charged with trying to pick up a seven-pound package of methamphetamine at a post office, U.S. Attorney Barry Grissom said today. 41 year-old Maria Descorro Martinez of Topeka is charged with one count of possession with intent to distribute methamphetamine. The crime is alleged to have occurred March 18, 2013, in Shawnee County, Kansas. Martinez initially was charged in a criminal complaint filed March 19, 2013, in U.S. District Court in Topeka. An agent’s affidavit stated that the Topeka Police Narcotics Squad had Martinez under surveillance on March 18, 2013, when she picked up a package containing methamphetamine at the post office at 2921 Adams in Topeka. Martinez did not know that earlier investigators had learned the package contained methamphetamine and they had obtained a search warrant. When they opened the package they found it contained seven pounds of methamphetamine. If convicted, she faces a penalty of not less than 10 years and not more than life and a fine up to $10 million. The Drug Enforcement Administration investigated. Assistant U.S. Attorney Greg Hough is prosecuting.
