In the shooting reenactment Cheri Manning is shown being shot in the upper right chest. But in the police station, when she is being interviewed, only her upper right arm is bandaged.
The investigators discover a coaxial cable splitter coming from a satellite dish "The guy was skanking my feed. I started to get billed for his pay-per-view porn." Splitting a signal from the dish wouldn't put the splitter's charges on the owner's bill. Signals are descrambled by the satellite receiver which is inside the dwelling. That is also where access control (via a smart card) and therefore billing are determined. The neighbor might be able to split the feed, but he'd have to have his own satellite receiver (and smart card account) to watch any programming from the dish.
After testing a fragment of newspaper used in a shooting, Wolfe states that commercial printers in the North East have just started to use soy ink. Therefore they surmise that the shooter came from the North East. Soy ink has been in use for over a decade in the US. Soy ink was not a valid clue.
The satellite dish appears to be pointed toward the north east (relative to the location of the ocean near Miami). It should be facing toward the south.
