This drug bust was the result of an ongoing investigation where surveillance was set up to watch the house in south Laredo where the drugs were. "The majority of the seize appears to be marijuana." 1,095 pounds of marijuana were taken from the home. 596 grams of heroin were also seized, which police say is rare to see a block of it. In addition, weapons were seized as well as wrapping. "The paraphernalia that they use to actually store and pack and redistribute marijuana like large caches of cellophane." Two people were arrested on charges of possession. 36 year old Gilardo Alonzo Lopez and 34 year old Maria Morales. Morales has been a substitute teacher with United Independent School District as recent as the beginning of this week. We talked to the school district who tells us Morales was employed on an "as needed basis". They said they will block her from subbing into the investigation is over. "The warm spring, summer seasons is where the harvest is going on in Mexico and this is all coming through here." Although the amount of drugs seized is large. For Laredo, Baeza says it's pretty normal. "If you realistically think about the demand and the large scale organization we're dealing with, this is probably just a drop in the bucket that we're taking down." He adds that once it's redistributed, it breaks up into smaller parts and that's the way it travels through the united states.
