The late Michelle McNamara was a true crime writer who died in 2016 before solving one of the subjects that obsessed her. McNamara was the sort of person who threw herself into a subject and didn't let up. She was also the wife of comedian Patton Oswalt, and today she would have loved to have been a fly on the wall when they caught "The Golden State Killer" decades after eluding the police:

A suspect has been arrested in connection to a decades-old cold case involving more than 10 people who were murdered, known as the Golden State Killer case.

Joseph James DeAngelo, 72, was arrested early Wednesday morning on two counts of murder, according to the Sacramento Bee and Fox40 Sacramento. A spokesperson for the Sacramento County Sheriff’s Department has not yet responded to TheWrap’s request for comment.

The Golden State Killer was linked by DNA and method to 12 murders, 45 sexual assaults and more than 120 burglaries from Sacramento to Orange County between 1976 and 1986.

This was one of the last things McNamara worked on before her passing:

The Golden State Killer case was also the subject of a true-crime book titled “I’ll Be Gone in the Dark,” by Michelle McNamara, Patton Oswalt’s late wife. McNamara worked with investigators on the case but died before the book was published. It was finished by co-writer Billy Jensen, researcher Paul Haynes and Oswalt.

In regards to news that an arrest had been made, Oswalt tweeted, “If they’ve really caught the #GoldenStateKiller I hope I get to visit him. Not to gloat or gawk — to ask him the questions that @TrueCrimeDiarywanted answered in her ‘Letter To An Old Man’ at the end of #IllBeGoneInTheDark.”

We can only hope that they got the right man, due in no small part to McNamara's work.
