Police say that on Friday night Scott Paul Beierle posed as a customer at the yoga studio and then suddenly started shooting people.
Charges were dismissed for both of Beierle's university arrests, but he agreed to a plea deal after a final arrest by Tallahassee police in 2016.
Police did not release more details about the calls involving Beierle.
First Coast News reports a witness saw a man run into a bar hyperventilating, followed shortly after by a blood-splattered man.
Mann says incels "move toward a very virulent misogyny, and they spend a lot of time engaging in really violent ideation about the frightful things that they want to do to women and sexually successful men".
Five people were killed on June 28, when a gunman stormed into the Capital Gazette newsroom in Annapolis.
The shooter had also praised shooter Elliot Rodger, who is largely seen as a hero amongst the so-called "incel" movement, a largely online-focused number of people who have declared themselves "involuntary celibate".
Scott Paul Beierle, 40, had also been accused of harassing women and grabbing their bottoms, police say. Tallahassee Police Chief Michael DeLeo said some in the studio showed courage and tried to stop him.
The investigation is ongoing, and police have yet to establish a link between the shooter and the victims and yoga business.
Emergency vehicles are parked outside the Hot Yoga studio at a shopping center where a guman opened fire in Tallahasee, Florida, U.S., November 2, 2018, in this still image taken from a video obtained from social media. "This monster ruined it".
The gunman appeared to have acted alone and there was no immediate threat to the Tallahassee community, Mr DeLeo said.
Beierle, who had served in the military, also uploaded a vide where he said he wanted to "blow off" a woman's head.
"You don't think about this in Tallahassee and now you have to", said Welling, 26, who lives in the neighbourhood. He said that he did not know him well but said he "definitely seemed angry and on edge".
The suspect fatally shot himself, DeLeo said. Police have not yet said what kind of gun he used.
FSU said her research was focused on restructuring healthcare for people with multiple chronic diseases.
The department identified the two people who were killed as Dr. Nancy Van Vessem, 61, and Maura Binkley, 21.
Two people who were in the hospital during the 1 a.m. press conference were in stable condition, DeLeo said in the video posted to the agency's Facebook page.
Maura Binkley, who grew up in Atlanta and was a double major in English and German, was set to graduate in May.
Court and FSU records show that Beierle had been previously arrested for grabbing women - and had once been banned from FSU's campus. A university police report shows that Beierle told police he may have accidentally bumped into someone, but denied grabbing anyone.
