Police have confirmed eye witness reports that Holmes was wearing a bullet proof vest and a gas mask at the time of the shooting, and was carrying four weapons with him.
A woman in San Diego, Calif. has since stepped forward to identify herself as the mother of a James Holmes, and despite not being contacted by authorities about the case she is adamant that the shooter is her son.
"You have the right person," she said to ABC News. "I need to call the police ... I need to fly out to Colorado."
In a statement released by the family, they say: "Our hearts go out to those who were involved in this tragedy and the family and friends of those involved."
His family have asked for privacy, saying they were "still trying to process this information."
A University of Colorado spokesman has told NBC News that Holmes was a graduate student in the neuroscience program at the university's Medical School. He was in fact in the process of withdrawing from school, the university confirmed.
"The University of Colorado Denver Aschutz Medical Campus can confirm that Mr. James Holmes was in the process of withdrawing from the University of Colorado Denver's graduate program in neurosciences," the university statement said. "Mr. Holmes enrolled at the university in June 2011."
Holmes reported to police upon his arrest that his apartment may have explosives in. Authorities have since reported that the apartment was booby-trapped with explosives when they went there to investigate. Trip wires and bottles of ammunition, and bottles of a mysterious liquid have also been found inside. As of Friday evening investigators and bomb experts were still trying to find a safe way to nullify the bomb threats and enter the apartment on foot. It is also reported that the FBI has about 100 agents currently assisting the investigation.
President Obama has canceled his agenda for the day on Friday and called on the nation to pray for the victims' families.
