A search on Monday that uncovered 3 1/2 pounds of methamphetamine was one of the largest caches ever found by Austin police, said Chief Brian Krueger.

“It is a very significant amount of meth taken off our streets,” he said.

Phaengdy Khamda, 35, faces possible felony charges of first-degree controlled substance after Monday’s bust. Khamda was at a residence on the 600 block of 10th Street Northeast when a search was executed at 1:17 p.m., Krueger said.

She is awaiting formal charges in the Mower County Jail.

Police found 3 pounds of the drug in three, 1-pound bags, and several other smaller bags that together weighed 6 1/2 ounces.

Krueger did not have a street value of the meth, but said “it is definitely among the bigger amounts” uncovered by police.

“I can say that I am very happy this is off the street,” he said.

Three children, ages 1, 2 and 3 years, were removed from the residence by Mower County Health and Human Services. Their relationship to the suspect is not clear, Krueger said. Another woman, identified as a grandmother to at least some of the children, was allowed to stay at the residence, Krueger said.

No details were available as to what led police to execute the warrant at that residence, but Krueger said that there were no other pending arrests at this time.
