Hunt 4 missing sci

there are two main characters not including me, one named Henery Einstein, and one just named Sandy. I have to hunt for the lost Sandy.. but later on while in in. an elevator going to the 17th floor of the 20 floor tall museum Sandy died supposedly on 1927 (unknown month) 17th. I said Sandy's name. the elevator stopped and a voice said "how do you know that name? you're alone so I'll let you go" meanwhile while while im with another friend he came along with me into the elevator to go to the 17th floor. he said Sandy and the elevator stopped. the person said "oh my.. looks like I have some new toys" and the elevator dropped. we both fell unconscious but when I woke up the elevator door was cracked open and there was a light. He opened the door and got out first, i came out second. we met this lady whose voice sounded strange, but I forgot what she said. but a little bit later. I feel tired and collapse from a smell.. thats all I know far.. (picture is Ai, dont listen to voice, and the I is what you are in this] l
