AURORA, Colo. — Aurora Police said they interviewed an associate of the suspect in the shooting spree Friday at the Century 16 Movie Theaters.

Sources tell FOX31 Denver reporter Justin Joseph that a second man is now a person-of-interest in the Aurora theater shooting investigation. But police say that is not the case.

“An associate of Holmes was interviewed this evening (Saturday),” says police spokeswoman Sgt. Cassidee Carlson. “There is no reason to believe that he is involved. Further details of this investigation will not be released at this time.”

Twelve people were killed and 58 injured early Friday when James Egan Holmes allegedly opened fire inside the crowded theater.

Neighbors of the suspect’s associate say for the past two days there have been SWAT team and police cars in their alley and unmarked cars in street.

“He’s been there about a year,” said one neighbor.

Agents showed up again Saturday morning.

“I woke up this morning with cops still here trying to look inside his home.  At 5:00 a.m. cops showed-up and asked me about (him).”

Sources tell Justin Joseph someone made either a call or a text from the person of interest’s phone threatening violence if James Egan Holmes was not released from jail. That call prompted police to issue an alert to find and detain him.

The associate’s Facebook page shows he has a master’s degree in bio-medical science.

Anshutz Medical Center confirms he is in their doctorate program, the same program from which Holmes withdrew several months ago.

Out of caution police searched their campus Friday, but they won’t say what if anything they were looking for or found.
