A crazed gunman killed two women during a hot yoga class in Tallahassee, Florida.
The shooter has been identified as 40-year-old Scott Paul Beierle.
Beierle shot himself dead after the fatal attack in which five others were injured.
It is believed the killings are linked to a domestic dispute involving the killer.
Binkley was a student at Florida State University and Dr Van Vessem was a faculty member.
University President John Thrasher said in a statement: “There are no words to express the shock and grief we feel after learning of the deaths of Maura Binkley and Dr. Nancy Van Vessem.
“To lose one of our students and one of our faculty members in this tragic and violent way is just devastating to the Florida State University family.
“We feel this loss profoundly and we send our deepest sympathies to Maura's and Nancy's loved ones while we pray for the recovery of those who were injured.'
Witness to the shooting Alex Redding revealed that he saw a woman run into the bar downstairs followed by a man with blood on his head.
He said two to three other people sought help nearby and they told him that a tall man with a beard was acting strangely in the studio and then began shooting.
