Update

Tandy's brother Matthew is in jail because everyone thinks that he murdered his girlfriend. Everyone thinks it was him because just like when his parents were murdered, no evidence of break in. When Tandy is investigating the murders of the girls from Private schools, she makes a break through that could potentially clear Matt's name and get him out of jail. "I have evidence of a murder. Put Caputo on the phone." When Tandy finds what she was looking for, she makes a call to Caputo the police investigator on the case. She tells him to come to Matt's apartment because she has found evidence of how/who killed Tammar Gee, Matt's girlfriend. I think that Matt's name will be cleared as long as the evidence that Tandy found holds.
