Sikh temple gunman's ex held on weapons charge

Updated at 2:04 p.m. ET

(CBS/AP) MILWAUKEE - The ex-girlfriend of a man who police say fatally shot six worshippers at a Sikh temple Sunday faces legal trouble herself.

South Milwaukee Police Chief Ann Wellins released a statement Tuesday saying 31-year-old nursing student Misty Cook had been arrested on a tentative charge of being a felon in possession of a firearm. Cook was the ex-girlfriend of Wade Michael Page, who was involved with white supremacy groups.

At a Wednesday morning news conference, the FBI's special agent in charge in Milwaukee, Teresa Carlson, told reporters that Cook was arrested Sunday after police officers observed a weapon in her home during an interview for the Page investigation.

Milwaukee County sheriff's spokeswoman Fran McLaughlin said the 31-year-old Cook also went by Brenda Cook. Online court records show Brenda Cook pleaded no contest in 2005 to a felony charge of fleeing an officer. Carlson said Misty Cook wasn't connected to the Sikh temple shooting and was cooperative.

The voicemail on Cook's cellphone was full and wouldn't accept a message. However, in regard to the shooting, she told the Milwaukee Journal Sentinel in an email: "If I could say something to ease the pain of the victims and their families, I would gladly do so. Unfortunately, words do not begin to heal the pain they are going through."

Carlson also told reporters that video footage from the shooting showed that Page apparently shot himself. Previously, Oak Creek Police Officer Sam Lenda was credited with downing Page. Lenda was the second officer who responded to the scene. Carlson said Lenda shot Page in the stomach.

At the moment, detectives are sifting through the gunman's life, assembling the biography of a man who apparently had few relatives, a spotty work history and a thin criminal record. They have warned they might never learn for certain what drove him to attack total strangers in a holy place. The Sikh community holds out hope.

"We just want to get to the bottom of what motivated him to do it," said Amardeep Singh, an executive with the New York-based Sikh Coalition. "It's important to acknowledge why they lost their lives."

The 40-year-old Army veteran strode into the Sikh Temple of Wisconsin shortly before Sunday services and opened fire with a 9 mm pistol. The dead included temple President Satwant Singh Kaleka, who was shot as he tried to fend off the shooter with a ceremonial knife, CBS News correspondent Ben Tracy reports.

Page wounded a responding police officer in the parking lot before another officer killed Page in a shootout.

The FBI has taken over the case and released little official information. The fragments of Page's past that have emerged suggest he lived a somewhat troubled life.

A native of Littleton, Colo., he had a record of minor alcohol-related crimes in Texas, Colorado and North Carolina. He was demoted during a stint in the Army for getting drunk on duty and going AWOL before he was discharged in 1998. Page eventually moved to Wisconsin, living in South Milwaukee with Cook and working third-shift at a brazing factory in Cudahy, another Milwaukee suburb.

Neighbors said the couple broke up this past spring. Page moved into a Cudahy duplex in mid-July and quit showing up for work around the same time. A few days after he moved into the duplex, he visited a West Allis gun shop and, after clearing background checks, bought the gun he used in the shooting.

The Southern Poverty Law Center has described Page as a "frustrated neo-Nazi" who participated in the white-power music scene, playing in bands called Definite Hate and End Apathy.

Rajwant Singh, chairman of the Sikh Council on Religion and Education, said even though Page is dead, other white-supremacy and neo-Nazi groups could harbor similar intentions.

"Our concern is, how do we tackle these hate groups operating underground or in darkness?" he said.

The FBI has classified the incident as domestic terrorism, a violent act for social or political gain. But the bureau hasn't said anything about Page's possible motives.

Now investigators face two tasks: determining what drove Page over the edge and whether anyone nudged him along the way.

Carlson said investigators have no information to suggest that anyone else was involved, but they continue to search to make sure.

Investigators probably will collect all the bullets and fragments from the temple and the victims' bodies to confirm that they came from Page's gun. Detectives also will pore over witness statements to make absolutely certain he was the only shooter, said Joe LeFevre, chairman of the forensic science department at Fox Valley Technical College in Appleton.

Authorities will interview Page's family, friends and associates. Agents spent Monday morning doing a door-to-door sweep on his street, chatting with neighbors on their front porches and in their backyards.

If agents seized a computer from his apartment, they likely will review the websites he visited and any writings he posted. If they recovered a cellphone, they will use it to follow his recent movements as the device shifted from one cell tower to the next.

"It's like any crime," said Jack Ryan, a Rhode Island attorney who trains police around the country. "You focus on their recent tracks. You focus on friends, acquaintances. He had to get ready for this plot somewhere."

The investigation could take weeks or longer. But Page's motive is the key.
