Juan+Tuno


 * Name:** Juan Tuno
 * Suspect?:** No, Juan is trying to prove who is killing the fish.
 * Background:** Lead investigator on the case. Using the chemistry test kit he received for his 13th birthday, he studied and tested the water in the Gray Area. He also enjoys going on the waterslide and wants to prove that Don Juan Tuno is innocent.

Detective

Juan did a biological test to determine whether or not the water slide was pouring chlorine into the river. He used daphnia as bioindicators because they are sensitive to changes in the environment. If the river wasn't being polluted by the chlorine, then there should have been as many daphnia downstream as there were upstream. However, there weren't.

Juan thinks that clear cutting is causing erosion and making the water too turbid for the fish to live in.

Juan believes cattle manure is killing the fish. Seven years ago, the number of cattle at the ranch increased. When the manure gets washed into the ponds and rivers, it causes phosphates. The phosphates give nutrients when they are alive, but when they die they take away the oxygen the fish need to live. With the high number of phosphates, there is a small amount of oxygen.

**__Introductory Statement:__**
I go to school in Synchrony City. I like science, but I also really like the water slide. When I heard that they might close down the water slide because fish are dying, I decided to do my own tests with my chemistry kit. I found chemicals called phosphates in the stream. I think they may be coming from my uncle’s cattle ranch, and killing the fish. It’s not fair to shut down the water slide if the cattle ranch is killing the fish.

I’m glad the test came out negative for chlorine downstream from the water slide, but just to make sure, I would like to do a biological test for chlorine, by checking for tiny animals that are called daphnia. Daphnia can’t live well in water with chlorine in it. If there’s no chlorine problems in the water downstream from the water slide, there should be as many daphnia there as there are upstream.

__Final Statement__
So I guess you reached the same conclusion I did. i found that the fish were killed by a combination of a few of the suspects. But I also decided that //I// am guilty. I feel real bad about it, but as I investigated I kept realizing that I'm to blame. I use the water slide, and the evidence seems to point at it as one of the problems. I ride in cars when I could bus, bike, or walk and the oil and acid rain evidence points to cars. The phosphates came from the golf course lawns, and I admit I've never paid any attention to fertilizer and how much watering happens on golf courses I've been to, or even on my own family's lawn. I don't hunt, but I have contributed to erosion by riding my bike on hills off trails. It's clear I'm going to to have to make some changes in what I do to help solve this problem. Not just me though, but also the suspect who I think is most responsible for the fish kill. And that suspect is...Avery Wun!
