Michelle McNamara passed away unexpectedly in her sleep on Thursday, in her home in Los Angeles.

McNamara was a true crime writer, and a graduate of Notre Dame, who received her master’s degree in creative writing from the University of Minnesota. True Crime Diary was a popular blog that McNamara started to support her own personal interest in studying breaking and cold cases. NBC News quotes her as saying:

It’s the ones that really don’t get that much attention that interest me because I think what’s interesting about them is there’s more stuff to be unearthed that hasn’t been in the public yet and you can do it.

McNamara married Patton Oswalt in 2005, and they have a seven-year-old daughter named Alice. Oswalt spent most of Thursday tweeting about Prince’s passing, then silence through Friday until he shared The Hollywood Reporter’s obituary for his wife. Many celebrities are expressing their love for Oswalt, and memories of the lovely person McNamara was:
