(CNN) — Authorities are on the hunt for a man accused of killing his girlfriend and then posting gruesome pictures of her body online.
The suspect has been identified as David Michael Kalac, 33. He is described as 6-feet 2-inches, 220 pounds, with brown hair and brown eyes.
Kalac is believed to be armed and dangerous, and driving the victim’s vehicle, a 2001 gold Ford Focus. He is being sought on suspicion of second-degree murder.
“Outside of a terrorist attack this is as serious as you can get,” said Deputy Scott Wilson, with the Kitsap County Sheriff’s Department.
Authorities first received a call Tuesday afternoon. Upon arriving at an apartment in Port Orange, Washington, they found the body of 30-year-old Amber Lynn Coplin.
Around the same time, authorities started receiving tips about suspicious photographs posted online on Imgur and 4chan, Wilson said.
“The initial poster, believed to be Kalac, was also posting comments with the pictures. He said that the crime scene would be discovered and what he was going to do. We took this very seriously. We have no reason to believe that anyone posted them but him,” the deputy said.
According to CNN affiliate KOMO, the statement read, in part: “Check the news for Port Orchard Washington in a few hours. Her son will be home from school soon. He’ll find her, then call the cops. I just wanted to share the pics before they find me. I bought a BB gun that looks realistic enough. When they come, I’ll pull it and it will be suicide by cop. I understand the doubts. Just check the (expletive) news. I have to lose my phone now.”
KOMO reported the same writer later added: “Turns out its way harder to strangle someone to death than it looks on the movies. She fought so Damn hard.”
Kalac has a history of domestic violence and making threats to law enforcement, Wilson said.
Agencies across the country are looking for him.
Early Wednesday morning, police in Portland, Oregon, were in pursuit of the victim’s vehicle, in all likelihood being driven by Kalac, Wilson said. The chase became dangerous, and they were forced to back off.
The vehicle was later found abandoned in the same city. Kalac remains at large.
