PICKET: Authorities search for 'second person of interest' seemingly involved in Colo. shooting - threatened violence if alleged shooter was not sprung

Fox 31 Denver is reporting that local state and federal authorities are looking for a second person of interest they believe may have been involved in the Aurora, Colorado theater shooting late Friday night:

Neighbors of the person of interest 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 this 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.
Sources also say a picture of Holmes with red hair on an adult website is what Egan looked like when he was arrested. 
Neighbors recognized him instantly but they say he recently dyed his hair.
“I`ve seen him before,” said a neighbor to the person of interest.
The person of interest’s Facebook page shows he has a master’s degree in bio-medical science.

James Eagan Holmes, a 24 year old former medical student, allegedly shot 71 people in a theater of at Aurora's Century 16 Cineplex during last Friday's midnight showing of The Dark Knight Rises. Twelve people were killed and 59 were injured. Holmes, gave up to authorities immediately and revealed his apartment was booby-trapped with explosives. On sunday afternoon, bomb squad experts managed to safely dismantle a complex series of trip wires and a number of incendiary devices in Holmes's apartment.
Holmes legally purchased four guns in the past two months, bought 3,000 rounds of ammunition for the assault rifle he bought, 3000 rounds for his Glock pistol as well as 300 shotgun rounds.
NBC's affiliate WKYC spoke to a witness on the scene of the shooting who told their reporter he saw an individual letting the gunman into the theater:

"As I was sitting down to get my seat, I noticed that a person came up to the front row, the front right, sat down, and as credits were going, it looked like he got a phone call. He went out toward the emergency exit doorway, which I thought was unusual to take a phone call. And it seemed like he probably pried it open, or probably did not let it latch all the way. As soon as the movie started, somebody came in, all black, gas mask, armor, and threw a gas can into the audience, and it went off, and then there were gunshots that took place."

The New York Daily News is reporting that Holmes has been kept in solitary confinement and spit at the guards. Apparently he is not making any friends and, according to recently released inmates, prisoners "were talking about killing him."
Holmes is expected to be appear in court on Monday for his arraignment.
