Patton Oswalt honored his late wife, Michelle McNamara, on Tuesday in an emotionally-charged tribute, where he opened up about her life and the powerful impact her absence has had on him and their 7-year-old daughter.

"The reaction to her passing, the people who are shocked at her senseless absence, is a testament to how she steered her life with joyous, wicked curiosity," Oswalt wrote in an editorial for Time magazine. "She hasn’t left a void. She’s left a blast crater."

McNamara, who tied the knot with the celebrated comedian in September 2005, passed away in her sleep on April 21 and the age of 46.

In his touching tribute, Oswalt also praised his wife's celebrated career as a true crime writer, detailing her talent for captivating prose.

"Michelle Eileen McNamara entered the world on April 14, 1970. On April 14, 2016 she turned 46. One week later she was gone. That’s the kind of opening Michelle would have written. She’d have done it better," the 47-year-old wrote. "She’d have done it better. Added one perfect adjective or geographical shading to pull you in. The pulling in of you, the reader, was never aggressive, calculating or desperate. She didn’t have to raise her voice."

"I loved her," Oswalt's heartfelt memorial continued. "This is the first time I’ve been able to use 'I' writing this. Probably because there hasn’t been much of an 'I' since the morning of April 21. There probably won’t be for a while. Whatever there is belongs to my daughter—to our daughter. Alice."

On Sunday, Oswalt took to Twitter to share some heartbreaking yet illuminating words from his young daughter, who told her dad days after McNamara's death, "When your mom dies you're the best memory of her. Everything you do is a memory of her."

Oswalt also shared his own brief tribute to his wife a week after her death, tweeting, "She wrote lines that stung & hummed. 13 years in her presence was happily humbling."

At the time of her death, McNamara was working on a book about the real-life murderer known as The Golden State Killer. "This was the project she was 2½ years into when her story stopped, sometime on the morning of April 21," Oswalt shared in the editorial.
