A woman on the jury that acquit Karen Read this week on murder and manslaughter charges spoke exclusively to ABC News, saying she believed “a collision did not occur.”

"I was happy for Karen Read and her family of course. I think justice was served," Prado said. "But seeing John O'Keefe's family leaving the courthouse, was melt my heart. I'm a mother and I saw her pain through all those days."

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.
