1The Felix Mystery: Case of the Missing Millionaire Investigated by the2011 Challenge Class
2Background Information Victim: Felix NavidadFelix was not very well-liked because he continually criticized everyone and everything around him.Felix inherited a considerable amount of money.Felix had just recently bought a two-bedroom one-bath beach house located in a very expensive neighborhood.Threw a weekend housewarming party for four of his closest friends.Although Felix considered these people to be his best friends, none of them liked him very much, and they probably only accepted the invitation because he had recently announced that they were all named equally in his will.
3Background Information All four of Felix’s guests are suspects in the case.When the police arrived, they found no external injuries and no blood on the victim’s body.The body disappeared on the way to the morgue, before an autopsy could be performed to figure out how he died.We not only don’t know who killed Felix, if it was a murder, but we don’t even know how he died!There is even some speculation that Felix is not dead, but staged the crime for his own reasons. Reports that he has been seen at the local bus station have not been confirmed.
4Alfredo FettuccineStatement: “My name is Alfredo and I am a computer programmer. I saw Felix sitting on the patio, so I joined him at about 2:00pm. We each had a can of cola, but we poured them into cups to drink. I set down my cup of cola and went to the bathroom at about 2:45pm. When I came back 10 minutes later, I found Felix lying dead on the floor, so I called out to the others at about 3:00.”What we knowAlfredo has a cut on his left hand.He has a brown felt pen in his pocket.He plays guitar.He was wearing tennis shoes and a blue sweater.
5Kendra GoodeStatement: “My name is Kendra and I am an artist. I went upstairs to take a shower in the bathroom at about 2:30pm. I think that I heard a woman’s voice downstairs. I came downstairs as soon as Alfredo called out at about 3:00.”What we knowKendra has white powder on her tennis shoes.She has pierced ears
6Gene PouleStatement: “My name is Gene and I am an office manager. I took my dog Sasha down to the beach for a walk at noon. After taking off my sandals, I fell asleep with Sasha lying next to me. When Alfredo called out at about 3:00pm, I woke up, and brought Sasha up right away. I never let Sasha come inside or on to the patio.”
7Vera CruiseStatement: “My name is Vera and I am a chemist. I went for a walk at about 2:00pm in the hills behind the house. I came back when I heard Alfredo call for help at about 3:00.”What we knowA white powder was found on Vera’s tennis shoe.Vera was wearing a white wool sweater.She loves candies with brown coatings.She has pierced ears.
8Investigation Steps Mapping the Crime Scene Collecting the Evidence Analyzing the EvidenceReconstructing the CrimeDrawing a Conclusion
12Mapping the Crime Scene We divided the crime scene into 8 sections and drew all of it.We paid attention to the details in the crime scene, like footprints, evidence, and the body formation.
13Collecting the Evidence Evidence CollectedThe following items were collected and put in bags:2 Coca-Cola cansGuitar pickWhite powder2 pieces of stringSnickers wrapperDog printsHuman foot printsPaint brush2 cups partly full of a brown liquidTrash canDog hairTowelPencil shavingsComb with hair on itFolderIce cube tray with water in itBody outlineBlood dripsNailsAlarm clockHairsunglasses
14Analyzing the Evidence We used the following tests to analyze the evidence:Fiber AnalysisFingerprintingpH TestingDNA AnalysisTape LiftsHandwriting AnalysisPowder RevealingChemistry ReactionsChromatography
15Fiber Analysis Fiber analysis is the study of fibers. We looked at fibers through a microscope. We were trying to find out if the fiber was cotton or wool.
16FingerprintingWe compared fingerprints from the suspects with fingerprints found at the crime scene.The crime scene fingerprints were found on Felix and Alfredo’s cups.Kendra’s prints were found on Felix’s cup, but not on Alfredo’s.The fingerprints were revealed by putting Krazy glue in a bag with the cup.
17Coca-Cola TestWe used pH paper to test the Coke in Felix and Alfredo’s cup.We compared it to normal Coke by dipping the pH paper in the real coke then in Alfredo’s and Felix’s cokes and comparing the reactions.We found out that Felix’s coke was different from regular coke.From left to right:Felix’s Normal Alfredo’s
18DNA AnalysisWe used DNA analysis to look at a sample of hair evidence and compare it to our suspects.The hair found on the comb was Felix’s. We know that because it matched the DNA sample of his hair.
19ChromatographyChromatography is when you color on a paper towel or napkin and then you stick the end of the paper towel in water and it absorbs the color and makes it easier to see and tell apart from other inks.We took a napkin that had black stuff on it and used chromatography to figure out if what was on the napkin was brown food coloring or brown marker.The napkin had food coloring on it.From left to right:Food coloring, evidence, brown pen
20Secret NoteWe found a secret note on the folder (evidence). The message was indented into the folder by someone writing on top of it.We used brown powder to reveal the note. We put it on and brushed it off carefully. We kept brushing and the message came clear.It said, “Dear Martha, The deed is done. Felix is dead and I’ll be rich soon. Love, Vera”
21Handwriting AnalysisThe secret note was written in regular handwriting and not cursive.We took samples of each suspect’s handwriting and found that Kendra’s (suspect) handwriting matched it most clearly.Kendra must have framed Vera because Vera’s name was on it.
22Tape LiftWe did a tape lift on every suspect’s shirt to look for fibers, hair, and other stuff.Kendra had dog hair and grass.Vera had a piece of hair in her hood.Gene had yarn and dog hair on him.Alfredo had dog hair and maybe grass.
23Ice Cube TestWe used pH paper on the ice cube water to compare it to tap water.We saw that the ice cube water was way different than the tap water.We think the ice cube water may have been poisoned by Kendra.Ice CubesNormalWater
24Powders TestWe compared powders to see which had been used to create the fake blood in the crime scene, and if the same powder was on Kendra and Vera’s shoes.We put drops of iodine onto samples of baking soda and cornstarch to compare reactions.The test showed that the powder used to make fake blood was the same as the powder on Kendra and Vera’s shoes – cornstarch.

26Based on the evidence found, we believe that Kendra poisoned Felix. Our FindingBased on the evidence found, we believe that Kendra poisoned Felix.We believe Kendra poisoned Felix by putting poisoned ice cubes in his drink while Alfredo was in the bathroom. She may have poisoned him to get money from his death because Felix had named each of the suspects equally in his will.We believe she led the blind dog, Sasha, into the house with the ripped “KG” towel that smelled like a man’s body spray (like the dog’s master) trying to frame Gene. She may have also used Gene’s shoes.Kendra also tried to frame Vera, writing a note but signing Vera’s name.The white powder found on Kendra and Vera’s shoes was the same powder that was used to make the fake blood drops found at the crime scene.
