(CNN) -- The man who allegedly attacked House Speaker Nancy Pelosi's husband early Friday posted memes and conspiracy theories on Facebook about Covid vaccines, the 2020 election and the January 6, 2021 attack on the Capitol, and an acquaintance told CNN that he seemed "out of touch with reality."David DePape, 42, was identified by police Friday as the suspect in the assault on Paul Pelosi at the speaker's San Francisco home.Two of DePape's relatives told CNN that DePape is estranged from his family, and confirmed that the Facebook account -- which was taken down by the social media company on Friday -- belonged to him.His stepfather, Gene DePape, said David DePape grew up in Powell River, British Columbia, and left Canada about 20 years ago to pursue a relationship that brought him to California."I really don't know what to think," the suspect's uncle, Mark DePape, said of his nephew's alleged attack on Pelosi. "Hopefully it's a scam.
I don't want to hear something like that."Last year, David DePape posted links on his Facebook page to multiple videos produced by My Pillow CEO Mike Lindell falsely alleging that the 2020 election was stolen.
