GREEN BAY, WI (WTAQ-WLUK) – The man who allegedly stabbed a police dog is still not competent to stand trial.
Sai Vang, 31, faces three charges, including causing injury to a police animal for the April 7, 2019, incident involving Pyro, a Green Bay Police K9 officer. He has pleaded not guilty.
Vang’s competency – his ability to understand the court proceedings and assist in his own defense – has been an ongoing issue in the case.
As he did at a hearing in December, Vang disagreed with the assessment, and said he believes is competent to stand trial.
Judge Timothy Hinkfuss ordered Vang to remain at the Winnebago Mental Health Institute for treatment. Vang’s status will be reviewed April 26.
Police were called to a west-side home on because Vang was threatening to kill his father. Vang refused to surrender, so police released Pyro to engage Vang. The dog bit Vang, Vang pulled a knife out of his waistband, and stabbed Pyro. An officer then used a taser on Vang, and he was taken into custody, according to the complaint.
During questioning, Vang repeatedly apologized for stabbing Pyro but said “he stabbed the dog on instinct, because he is scared of dogs,” the complaint states.
