Click here for a look back at all of the weekend’s developments in the Brown University shooting investigation. What to KnowA shooter dressed in black killed at least two people and wounded nine others in a classroom at Brown University on Saturday during final exams.School officials said they were told that 10 people who were shot were students. An 11th person was injured by fragments from the shooting, but it wasn’t immediately clear if that victim was a student.A person of interest who was taken into custody on Sunday morning has been released after authorities determined the evidence pointed “in a different direction.” Police renewed their search Monday for the gunman who killed two Brown University students and wounded nine others, a day after they released a person of interest after determining the evidence pointed “in a different direction.” Authorities announced the man’s release at news conference late Sunday, marking a setback in the investigation into Saturday’s attack on the Ivy League school’s campus.

The lockdown, which stretched into the night, was lifted early Sunday, but authorities have not yet released information about a potential motive.
