-- Patton Oswalt paid tribute to his late wife, Michelle McNamara, on Twitter today.
McNamara, a crime writer, died last week at home in Los Angeles, the Associated Press reported.
No cause of death was given.
"She wrote lines that stung & hummed. 13 years in her presence was happily humbling. #RIPMichelleMcNamara," Oswalt wrote.
Oswalt, 47, and McNamara, 46, were married in 2005. They had one child, daughter Alice, who was born in 2009.
The actor also retweeted a link to 826LA, an arts organization accepting donations on McNamara's behalf.
"826LA encourages young writers to explore their creativity and improve their writing skills, and helps teachers get their classes excited about writing. A donation to 826LA in Michelle’s honor helps push forward her creative legacy," reads the website. "On behalf of Michelle, Patton, and Alice, we thank you for your donation."
