"And I saw this as one of those complex problems", Komos says.
"I don't remember exactly what he said, something like 'don't scream, '" the woman recalled.
Michelle McNamara had made it her mission to find the person responsible for at least 12 murders and 50 rapes throughout California in the 1970s and 80s. McNamara, 46, died in 2016, leaving the book unfinished. It became a No. 1 New York Times best-seller.
Joseph James DeAngelo, 72, a former police officer, was arrested Tuesday night and booked on two counts of murder Wednesday in Sacramento County. A DNA sample collected from the scene more than a decade later ultimately revealed it was the Golden State Killer.
Neighbor Barbara Wammer, 73, said DeAngelo built model airplanes that can be flown by remote control in the home he owned since 1983.
Kevin Tapia said when he was a teenager, DeAngelo falsely accused him of throwing things over their shared fence, prompting a heated exchange between DeAngelo and his father.
Tapia says DeAngelo was a "weird guy" and kept to himself.
"Not at anybody, just (expressing) his self-frustration", explained Natalia Bedes-Correnti, who lives just a few houses down from the alleged murderer and rapist.
Jones said DeAngelo was arrested outside of his home in Citrus Heights, a city near Sacramento.
Sacramento County Sheriff Scott Jones credited the book with helping to generate new tips but said no information was "extracted from that book that directly led to the apprehension".
DeAngelo served as a police officer in Exeter, California, from 1973 to 1976 and in Auburn, California, from 1976 to 1979, when he was sacked for shoplifting a hammer and a can of dog repellent, Jones said. That serial criminal was tied to burglaries and one killing.
Most of the early attacks occurred in the area of Sacramento, but the Federal Bureau of Investigation said DNA evidence had connected the suspect to a series of rapes and murders in the San Francisco Bay area and the southern part of the state.
"All too often we forget to talk about the victims and today we at least brought the first step towards closure for those victims of these horrendous crimes", Jones said.
For Santa Cruz resident Jennifer Carole, the tsunami of emotions began as a deluge of text messages early Wednesday morning, telling her that the capture of the man known as both the Golden State Killer and the East Area Rapist was "all over the news".
California authorities say a man they suspect of being a serial killer tied to dozens of slayings and sexual assaults in the 1970s and '80s has been charged with murder.
The case was cracked in the past week, when investigators matched DeAngelo's DNA with two murders in 1980.
However, she does not want the killer to face the death penalty.
Police believe the East Area Rapist killed the Maggiores after the couple - who were walking their dog at the time - spotted him before he broke into a home in Rancho Cordova, California, just outside Sacramento, in February 1978. She received the call from the Ventura County District Attorney's Office about 11 a.m. Wednesday.
Authorities are expected to announce the arrest Wednesday of a suspect in the decades-old East Area Rapist case, The Bee has learned. The attacks expanded to the Bay Area in late 1978. "The answer has always been in Sacramento", Sacramento District Attorney Anne Marie Schubert said.
McNamara's husband, actor and comedian Patton Oswalt, welcomed the news of the arrest and said on Twitter he was flying to Sacramento for the press conference.
The Sacramento County Sheriff's Department could not immediately be reached for comment.
The method of attack involved breaking into victims' homes as they slept, shining a flashlight into their faces, and tying them up, according to the Federal Bureau of Investigation.
