Broward County police admitted that even more warning flags were missed that could have prevented  the horrible shooting by Nikolas Cruz at a Florida high school .
The Miami Herald reports that a tipster called the Broward Sheriffâs Office warning them that  Cruz  âcould be a school shooter in the making.â Deputies neglected to write up the warning in a report.
Two weeks prior to that tip being called in  a relative of  Cruz  also told police that they should seize his weapons.
Astoundingly  a third report was missed when two years before  the shooting a deputy  investigated a warning about  Cruz  saying  he  âplanned to shoot up the school.â
Output:
Nikolas Cruz
