Michelle McNamara passed away suddenly in April 2016.
She said friends and family who supported her through the ordeal in 1979 were en route to her current Bay Area residence to hug her and celebrate the arrest. It became a No. 1 New York Times bestseller.
Patton Oswalt disagrees. He said so on Twitter and also during his previously scheduled appearance on Late Night with Seth Meyers.
Throughout their tour, McNamara and Holes talked DNA, the possible "geographic profiling" of the suspect, bloodhounds, tire tracks and the skill the man sometimes demonstrated in gaining entrance to the homes - and then evading police.
The prescription medication she was taking for the stress and anxiety likely contributed to her death at 46, he said.
Now that a suspect in the killings has been identified, Oswalt said he felt a unusual mix of elation and impending sadness that McNamara was not alive to witness it.
He might consider attending any trials of the accused killer Joseph DeAngelo, specifically on his mother and Sanchez' case.
"And now, you know, because he's been caught, now they can start linking him to all these other cases". She attributes his arrest to innovative new DNA processes along with "good old fashioned" police work. McNamara, the late wife of Patton Oswalt, was fascinated by the case and wrote I'll Be Gone in the Dark about her search for the killer. Police arrested Joseph James, DeAngelo, a 72-year-old ex-cop, after DNA samples discarded from his house matched old evidence from the Golden State Killer's crimes.More news: Cuomo threatens to sue ICE
In addition, police in the central California farming town of Visalia said Thursday that DeAngelo is a suspect in a 13th killing and about 100 burglaries in the area.
For years, she and her girlfriends have been amateur sleuths, getting together to review clues, like the diamond knots he tied, his short hair and corduroy trousers.
DeAngelo appeared in court Friday to face murder charges.
He said the high-profile arrest of DeAngelo should raise legal and privacy concerns for the millions who have submitted their DNA to an ancestry site database as there are no strong privacy laws to keep police from trolling. At the latter end of the 12-year span, similar crimes were committed further south which were linked to the Golden State Killer through DNA in 2000, though investigators were unable to produce a suspect.
Even if her leads don't turn out to have cracked it for investigators, her more ephemeral contributions certainly kept media and public attention on the case that McNamara found so chilling.
Officials initially did not disclose how their investigation led to DeAngelo, whose DNA had never previously been collected. It was just coming into use as a criminal investigative tool in 1986 when the predator variously known as the East Area Rapist and the Golden State Killer apparently ended his decade-long wave of attacks.
"I don't like that they thought that my dad was the bad guy, but the truth is they were able to rule out people in my dad's (family) tree", she said.
As early as 2013, writer Michelle McNamara was concerned that her book, I'll Be Gone in the Dark, about a serial murderer in California, might have an unsatisfying ending.
