The RCMP intentionally held back key details including the number of victims and evaded questions officers knew the answers to in the early days following the mass shooting in April 2020, a public inquiry into the tragedy has found.

An RCMP constable who alerted colleagues there might be a back way out of Portapique, N.S., on the first night of the 2020 mass killingsays it was such a hectic night, she doesn't remember making the radio broadcast.

A panel of four first responders spoke candidly about how the Portapique, N.S., mass shooting that left 22 people dead and changed the way they approach their jobs. They say their employer did not do enough to support them in the aftermath, or review its response to prepare for future emergencies.

The former director of communications for the RCMP, who previously told the public inquiry she "wouldn't change a thing" about the way communications were handled during the mass shootings of April 2020, testified about room for improvementwhile reflecting on how long it took to tweet about the gunman's replica cruiser.

Jennifer Clarke, a now retired corporal, testified Tuesday at the Mass Casualty Commission about what was happening behind the scenes before she tweeted about the gunman's replica cruiser.
