EL CAJON, Calif. -- An El Cajon woman accused of fatally shooting her neighbor in Denver six years ago did not fight extradition to Colorado to face a murder charge, 10News reported.

Thanks to the help from the public, Malaika Griffin, a murder suspect profiled on "America's Most Wanted," was arrested in El Cajon, authorities said.

Griffin, 34, was arrested at her apartment on Roanoke Avenue in El Cajon at about 5 p.m. Sunday, according to FBI Special Agent Jan Caldwell. She was booked into Las Colinas Jail on murder charges.

People living in the El Cajon apartment building said they had no idea their neighbor was wanted for murder.

"You know, you see it on TV and it doesn't seem real until it happens in your own back yard," neighbor Brian Moore said.

Griffin was sought in connection with the slaying of her 25-year-old neighbor, Jason Horsley, on May 18, 1999, in Denver, Caldwell said. Griffin was profiled on "America's Most Wanted" Saturday night.

Witnesses to the killing said Griffin argued with the victim in front of their homes, according to authorities. Griffin then got a 9 mm pistol from her home and fatally shot Horsley in the back, Caldwell said.

"She was very dangerous, and if she actually did commit the crime for which she's charged, she is a very very dangerous person," Caldwell said.

Denver authorities found a cache of weapons inside Griffin's room, including an assault rifle and grenades, according to "America's Most Wanted." They also found terrorist literature about a coming race war and journals in Griffin's handwriting about killing white people, according to the program.

Griffin allegedly carjacked an acquaintance's vehicle at gunpoint and drove to Iowa, Caldwell said. She was seen in Chicago before turning up in El Cajon, Caldwell said.

Several tips helped FBI agents find Griffin, who was arrested without putting up a fight, Caldwell said.

Monday would have been Horsley's 32nd birthday, 10News reported.

It was unclear how long Griffin had been living in El Cajon. She was working at a local biotechnology firm under a fake name, according to Caldwell, who said the suspect had graduated at the top of her class with a chemistry degree from Jackson State University in Mississippi. She also worked at two local fast-food restaurants.

Griffin's extradition papers were signed during a short hearing before Judge David Szumowski at the San Diego County Courthouse.
