On Sunday, comedian Patton Oswalt shared some very wise – and heartbreaking – words of wisdom from his 7-year-old daughter, Alice, about the sudden death of her mom, and Oswalt’s wife, Michelle McNamara. 
 
 “When your mom dies you’re the best memory of her,” Alice said, according to a tweet from Oswalt. “Everything you do is a memory of her.”

 NEW YORK (AP) — Michelle McNamara, a crime writer and wife of comedian and actor Patton Oswalt, has died at her home in Los Angeles, according to Oswalt's publicist. McNamara was 46. 
 
 Kevin McLaughlin of Main Stage Public Relations said Friday that McNamara died in her sleep Thursday. No cause was given but McLaughlin said her passing "was a complete shock to her family and friends, who loved her dearly." 
 
 McNamara graduated from the University of Notre Dame and received a master's degree in creative writing from the University of Minnesota. She founded the website True Crime Diary, which covers both breaking stories and cold cases. 
 
 In a 2007 online interview, McNamara said she started the blog almost as a lark. "I wanted to get more involved in the cases that were fueling my own curiosity," she said. 
 
 She didn't focus on the big celebrity murder case but ones that were smaller and out of the public eye. She wrote about the Golden State Killer and the 1976 murder of nurse Melanie Howell. 
 
 "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," she wrote. 
 
 Oswalt is a comedian whose TV credits include "Veep," ''Agents of S.H.I.E.L.D." and "The King of Queens" and films including "Magnolia," ''Starsky & Hutch" and "Ratatouille." McNamara and Oswalt married in 2005. 
 
 Along with her husband, McNamara is survived by a 7-year-old daughter, Alice.
