I only thought this witness was neutralized some others were credible and others pulverized. As to dingledorf, which one are you referrring to? Damon, Brenda, Denise, dog handlers, detectives, polygraph guy Redden who "wasn't taking a statement" Technicians who didn't wear booties and went from location to location, person who didn't see shell casing one day but saw it later, computer expert who I was told by computer person hasn't a clue about what he was speaking, police officers reports that repeatedly were contradicted by witnesses? Or Prosecution who didn't check possible exculpatory evidence..hair fingerprints etc. I believe this is a poor example of justice, more like JUST US whatever the outcome.
As for Danielle's friends, that remains to be seem, imo more likely for an adult to testify, but most neighbors will be hesitant to testify to anything helpful to DW...jmo.
