COURTESY PHOTO: MCSO - Marion County Sheriff's Office K-9, Yo, who died recently, is pictured here with Senior Deputy Jerry Wollenschlaeger after receiving the lifesaving award for his role in a 2014 rescue of a suicidal woman.Friends, family and co-workers from all over Marion County gathered Feb. 8 to stand alongside Senior Deputy Jerry Wollenschlaeger as he said goodbye to his best friend and K-9 partner Yo.

Yo, an, 11 year old Belgian Malinois, had to be put to sleep after being diagnosed with an untreatable form of cancer following a recent medical procedure.

Yo came to the Marion County Sheriff’s Office about nine years ago and is credited with over 150 captures. After each capture, Wollenschlaeger and Yo had a special routine where they would drive through and buy a cheeseburger to be enjoyed by Yo for his hard day’s work.

In just one example of Yo’s bravery, Wollenschlaeger was patrolling when a male, high on mushrooms, jumped through the open window of his patrol car and began attacking Wollenschlaeger. Yo was released from the back of the patrol car and came to the deputy’s aid. Yo seized the male, which distracted him long enough that Wollenschlaeger could gain control of his attacker.

In 2014, Yo successfully tracked and found a female threatening suicide. For his actions in this instance, Yo was given the lifesaving award.

Yo was a regular and crowd favorite at K-9 presentations, school events and a face you always loved to see running around the sheriff’s office.
