Maybe not the _only_ reason he got caught, but a major reason is exactly what OP mentioned: the victim was a member of the 1%.
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.
