SPEAKER_3 (1:28)
What training did you complete to become a law enforcement officer in Ohio?
David Laycox (1:32)
I had to go to the K9 Academy, which is roughly about 160 hours. A little bit of a long time.
SPEAKER_3 (1:40)
And any academy prior to that, prior to the K9 Academy, just the Iowa Police Officer?
David Laycox (1:44)
Correct, yeah, the Iowa Police Officer.
SPEAKER_3 (1:47)
And other than the K9 training, any other specialized training beyond basic academy training?
David Laycox (1:57)
I've worked on evidence. I've done all the normal police stuff, probably everything else I've done.
SPEAKER_3 (2:06)
Normal police stuff?
David Laycox (2:07)
Yeah, I think you're an example. Interview interrogation classes, we've went through evidence training, just basic police stuff at this point.
SPEAKER_3 (2:22)
Any special awards or medals or anything that you've achieved in your career as a police officer?
David Laycox (2:28)
I had multiple life-saving awards.
I received a distinguished service medal for assisting the fire department with saving a nine-year-old Apple issues 90, elderly female, house buyer. And then I received the BSSA Medal of Honor for entering upon a vehicle with two victims trapped inside a vehicle.
SPEAKER_3 (2:52)
And you mentioned that you're a K9 handler, and you mentioned the training. Can you repeat what training exactly you had to do to become certified as a K9 handler?
David Laycox (3:00)
So to be certified as a K9 handler, I had to go through the K9 Academy, which is about 160 hours of training service, roughly a little over a month long. I then have to continue every month for 16 hours, continue that education, train and track with my dog, and then get to be certified through a pilot every single year.
SPEAKER_3 (3:21)
And you said that you've been doing this for about three years?
David Laycox (3:24)
Yes, sir.
SPEAKER_3 (3:24)
And is this training individual or are you with the K9?
David Laycox (3:28)
I'm with the K9.
SPEAKER_3 (3:29)
And is that K9 the same K9 that is currently with you? Yes, sir. Okay. And so you're currently certified as a K9 handler?
What's the name of your K9?
David Laycox (3:47)
K9 Hayes.
SPEAKER_3 (3:48)
K9 Hayes. And what kind of dog is that?
David Laycox (3:53)
K9Hayes is a blackout.
SPEAKER_3 (3:55)
How long have you worked with K9Hayes? Three years?
David Laycox (3:57)
Yeah, three years.
SPEAKER_3 (3:58)
And how old is K9Hayes?
David Laycox (4:00)
He just turned four.
SPEAKER_3 (4:02)
And so you receive certification and training, does the K9 Retreat receive certification training as well?
David Laycox (4:08)
We get certification training together.
SPEAKER_3 (4:10)
Together, but in joint certification?
David Laycox (4:12)
Yeah, joint certification.
SPEAKER_3 (4:18)
Continuing education.
David Laycox (4:19)
Yes, that's right. We have to train together. It takes 16 hours every month and continue to train to get the fired hours and also be re-certified every single year.
SPEAKER_3 (4:36)
And what is tracking as it relates to K9 work?
David Laycox (4:40)
Well, in my case, they're with my dog, he's what? So we do tracking and trailing. Tracking is where I know what the suspect is supposedly started and my dog takes the track and we follow that track.
The other one is a trail where I don't know where the suspect's at. He does not do scent discrimination, so therefore I can get him an article, such as a piece of clothing, LOK, something of the person that's missing and he'd be able to scent discriminate, scent the air, get out of the trap in that way.
SPEAKER_3 (5:15)
So would it be fair to say that generally speaking a track is when there's an unknown suspect and a trail is when there's a known suspect?
