A man charged with four counts of first-degree murder remains the subject of an intense manhunt in Kansas and Missouri.
Authorities are looking for Pablo Antonio Serrano-Vitorino, 36, whom police have described as “armed and dangerous” and possibly carrying an AK-47.
Investigators from the Kansas City, Kansas, police department said Serrano is the suspect in a quadruple fatal shooting in the early-morning hours Tuesday. Three men died at the scene and one died at a hospital.
The identities of the victims are being withheld pending notification of next of kin.
CNN affiliate KCTV reported that, according to police, Serrano lived next door to the home where the killings took place. Officer Thomas Tomasic told the Kansas City station that it is unknown what prompted the shootings.
Serrano-Vitorino’s truck was found on I-70 near Montgomery County Missouri, approximately 170 miles east of Kansas City.
The suspect might be involved in the death of a fifth man, a spokesman for the Missouri State Highway Patrol said.
Lt. Paul Reinsch told CNN that a 49-year-old Montgomery County man was found dead in a home near where officers found Serrano-Vitorino’s truck.
Reinsch wouldn’t say how the man died. He said there was no indication of any vehicles or anything else being stolen from the home or nearby properties.
Serrano-Vitorino was last seen wearing a red and black flannel jacket, blue hooded sweatshirt and possibly blue jeans, authorities said. About 100 officers are searching for Serrano,
They warned citizens that he might be carrying an AK-47. Anyone who thinks they have seen the suspect should call 911, *55, or 816-474-TIPS (8477).
