They soured the lake every day for several weeks until August 24, at which point they brought in three cadaver dogs and an experienced dive time according to a statement by Sheriff Mark Podoll.
The search continued through the summer but by the end of September there was still no trace of Borgwardt.
Keith Cormican, founder of Bruce’s Legacy, went to Green Lake County Sheriff Mark Podoll on October 4.
“Sir, I’ve done a lot of searches and I can’t find him,” Cormican explained. Cormican wasn’t ready to give up; he requested additional sonar technology to continue in his search of the lake for Borgwardt.uni
It was around this time that Sheriff Podoll began to suspect something was amiss. On October 7, he gathered his crew, suggesting it was time they considered other possibilities. Shortly thereafter, they found records showing his passport was checked by Canadian authorities the day after his disappearance.
