Survivors of a high school shooting were plunged into terror once again when a gunman launched an attack killing two at their university campus.

Several students at Florida State University, where the stepson of a sheriff’s deputy carried out a mass shooting, were present at the Parkland shooting in Florida seven years ago.

Six other people were wounded when a 20-year-old opened fire at around lunchtime on Thursday, using a handgun owned by his stepmother.

For the second time in just over seven years, Lori Alhadeff received a text message saying there was an active shooter where her child was studying.

Her 14-year-old daughter Alyssa was one of the 17 people killed at Marjory Stoneman Douglas (MSD) High School.
