Four people were found murdered in the Kayenta area in one 12-hour period that started on Thursday night and stretched into Friday.
The four victims -- two men and two women -- were killed in three separate and unrelated incidents, according to information from the FBI.
"To have four murders in one district in 12 hours would probably be unusual in New York City, so to have that many murders in the Kayenta District is unusual," said FBI Special Agent in Charge MacDonald Rominger.
The small community on the Navajo Nation is about 25 miles south of Monument Valley and has a population of around 5,200.
The first homicide was reported on Thursday night in Kayenta, with one victim reported dead at the scene and another transported to the Flagstaff Medical Center for treatment. The second two homicide reports came in almost simultaneously on Friday, according to FBI officials.
Two people were killed in an apparent double-homicide at Inscription House and the other suspected homicide was reported at Black Mesa.
All of the murders were within the Kayenta District. FBI officials say they are now working with the Kayenta Police Department and the Kayenta Department of Criminal Investigations to track down leads.
Rominger said Monday that autopsies are scheduled this week for the two men and two women. The identities of the victims haven't been released.
"We have no one in custody in any one of the three homicide (incidents), but we're tracking down all logical leads at the present time, and we're awaiting some further information from the medical examiner's office," Rominger said.
