On March 25, 2020 Sacramento County Park Rangers received a call about a transient male in Discovery Park punching and slamming a small puppy.
Three minutes later rangers arrived and Douglas Thumm was in the middle of a park roadway with a pull cart containing a small female puppy. With his back to the rangers, Thumm was bent over the cart repeatedly punching the animal in its face. The puppy could not escape the abuse. THUMM was able to punch the puppy 4-5 times before stopping the abuse upon ranger commands.
Animal Control took possession of the puppy and Thumm was transported to the jail for felony animal abuse. The puppy survived.
Thumm is transient and has an extensive record in several states. He has been frequently contacted in the homeless encampments. He is known to set grass fires and is sex registrant out of state. He failed to appear for court after being released after arrest, due to covid emergency bail schedule.
