Books written by the suspect in the shootings who killed five people and injured two others in Denver on Monday are now part of the investigation.
The man, Lyndon James McLeod, 47, appears to have written a series of books that included details similar to the events of the killing spree. McLeod is believed to have written the books under the pseudonym "Roman McClay," Denver police confirmed Thursday.
A website dedicated to the series remained online Thursday, but links to the Amazon store where the books were being sold were no longer working.
In the first novel, "Sanction I," a character named Lyndon stalks a poker party held by a character named “Michael Swinyard” and gains access to a building near Cheesman Park by posing as a police officer. He fatally shoots everyone at the party and robs them before he flees with his dog in a van.
A man named Michael Swinyard, 67, was among the victims identified by Denver police.
In his second novel, which also features a character named Lyndon, McClay names Alicia Cardenas as a victim. The book also mentions the tattoo shop she owned, Sol Tribe.
The rampage began Monday after 5 p.m., when two women were fatally shot and a man was injured in a business near downtown Denver. The business was the Sol Tribe tattoo shop, NBC affiliate KUSA of Denver reported.
Alicia Cardenas, a tattoo artist at the shop, was identified as one of the women who were killed. Alyssa Gunn, 35, was also killed at the shop, police said.
Based on a preliminary probe, investigators determined that McLeod was “targeting specific people,” Denver Police Cmdr. Matt Clark said Wednesday.
Authorities say McLeod is believed to have gone on a killing spree in the area, evading police multiple times as he terrorized people's homes and multiple businesses. Police killed him after the gunman opened fire at a Hyatt House hotel, where a clerk was fatally shot.
Lakewood Police Agent Ashley Ferris shot McLeod after the gunman fire and wounded her. Ferris was stable and recovering with her family, the police department said Wednesday.
