This crime could have been solved the exact same way in the 1980s. The only difference being that the guy's picture would have been distributed over the 6 o'clock news instead of the internet.
And they also made use of other tech, like the fact that the Citibike has GPS.
Sure thing. They would know what the guy who kinda look like a photo of a wanted man is called. Doesn’t necessarily means they can pin anything on him. Obviously increases their chances, since they can work both backwards and forwards, but that is about it.
Assuming of course that the “he got just unlucky, a random person recognised them” is true, and not paralel construction for some other mean they don’t want to reveal.
\s murder is wrong
Waaay back in the late-80s, I was at an underground dance party. Some dude shot and killed another dude in the parking lot. At least a dozen witnesses saw it (I only heard it). Everyone knew the identities of both people involved. No arrests were ever made. I saw the dude on the street a few years later, walking around like he never shot and killed someone - thanks to the fine work of the Modesto PD.
