ammunition. jim. cnn has obtained police video related to the man charged in the killing of four idaho college students. there they are. the suspect, bryan kohberger, is seen in the video talking his way out of a traffic ticket one month before the gruesome stabbings. police have released other video and documents related to the suspect. cnn s jean caceres has been pouring through them. i wonder, what are the most significant findings from the videos and documents? reporter: it is 166 pages and there are things we had not known before. first of all, when they executed the searches at bryan kohberger s apartment in pullman, washington, they tested over 60 reddish brown stains in that apartment, presumptive blood testing. this is preliminary testing. they actually found two stains that tested positive preliminarily for blood, and one was a reddish brown stain on an uncased pillow in other words
a pillow without a pillowcase and then a brown, irregular drip found on a mattress cover. those stains were collected and then taken to the idaho state crime lab for further testing. we don t know the results of that. they also said that when they were searching that apartment that it was very sparse. it was as though it was empty of belongings. there wasn t a shower curtain in the bathroom, nothing was in any trash can, but they did collect what was there. also of note, in january the defense team asked two times to go to that apartment with law enforcement. kohberger had given them authority to go in those two times, and they collected things they did, the defense such as a receipt inside a medicine cabinet. there was a box that had papers in it, a flat screen television, a computer, also a small book of miscellaneous papers. so they have their items also which is interesting. so none of that definitively
amazingly well preserved. i mean, it s pretty fantastic to stand there and hold a sample like that because it really hits home that this is actually a real animal that used to live up here in the high arctic not that long ago. researchers have analysed the dna of 23 woolly mammoths uncovered in the siberian permafrost. so, what have they learned? well, as the mammoths evolved, their fur became fluffier and their ears became smaller. they probably had reddish brown hairand dry earwax. and, curiously enough, they may not have suffered from bo. the reason that humans have that body odour is that this protein is excreted into the armpits when we sweat and there is no reason to believe that woolly mammoths were actually sweating in their armpits or anything like that. they probably regulated their temperature in different ways.
