I store unlocked bike under the porch stairs in my locked fenced in yard. Around 3:30pm I saw an older black man in a long sleeve black shirt with a grey backpack riding my aqua retrospec bike in front of my house on s. Greenwood ave. I immediately recognized my bike because it is girly and has a distinct black basket- and I hollered after him "What the fuck, I can see you!" I did not see how he broke into the yard, but heard the gate clang as he left. I ran out and saw all of my belongings from the basket scattered in my yard. He turned left onto 65th st and turned south down the alleyway between Ellis and S Greenwood. I used a divvy to try and catch up and find my bike, thinking he would throw it because I saw him steal it, and also it is notorious for popped tires and riding down the alley would be risky with how flat the tires are right now. By the time I followed him, I lost him. A mail lady may have seen turn down 68th street. I uploaded a picture from when it was new. It no longer has a yellow basket or like-new shine. I am on a new set of handlebar grips which have ripped on the end and slide towards the center. Its a little rustier looking, and says retrospec in white on the base. It has a wide brown cruiser seat seat which has a water stain, and doesnt move up and down, which is why he looked a goddamn fool and caught my eye trying to ride it. Please help find it, I am a poor grad student!
