Boston Police Officer John O'Keefe, his girlfriend Karen Read and a group of other friends, including fellow officers, went out drinking at C.F. McCarthy's bar in Canton, Massachusetts at around 9 p.m. A major snowstorm had begun.

Karen Read’s second murder trial was a rematch for the lawyers after the first ended in a hung jury last year. CNN correspondent Jean Casarez answers key questions about the case after Read was acquitted of murder Wednesday.

Proctor told NBC’s “Dateline” that the idea he is corrupt and framed Read is a “ridiculous” accusation. He specifically said an accusation that he cracked Read’s taillight to make it look like she backed into O’Keefe is “absolutely not” true.
