Authorities in Virginia say two missing women and a missing teenage girl were shot to death by a carnival worker who met the victims through the traveling show.
James Michael Wright, 23, is accused of killing the women in February and March near his home in a far western corner of rural Virginia.
"Basically, this individual killed three women within about an 18-day period," Washington County Sheriff Fred Newman said at a news conference Monday.
Newman said the killings stopped shortly after Wright's truck was damaged in an accident. He said Wright could be classified as a serial killer.
Wright became acquainted with two of the victims through working as a subcontractor for the James H. Drew Carnival, the sheriff said. The 17-year-old was the daughter of one of Wright's co-workers.
Newman identified the victims as 25-year-old Athina Hopson of Johnson City, Tennessee; 22-year-old Elizabeth Marie Vanmeter of Carter County, Tennessee; and 17-year-old Joslyn M. Alsup of Cobb County, Georgia. All three had been reported missing in March.
Newman said the investigation is continuing into Wright's activities with the Georgia-based carnival, which he said traveled extensively.
"We have plans of contacting jurisdictions where that carnival very well may have been to see if they have missing persons," Newman said.
The carnival's owners did not immediately respond to a phone message seeking comment.
The investigation into Wright began about two weeks ago, authorities said. Police in Johnson City, Tennessee, who were searching for Hopson, zeroed in on Wright because he was the last person seen with her.
A police interview with Wright led to a search of his truck. Hopson's cellphone was found inside, police said.
Wright eventually confessed to killing Hopson and the two other women, Vanmeter and Alsup, police said.
Two bodies were recovered near Wright's home, one from a shallow grave and another near some logs, police said.
Authorities say they are still looking for Hopson's remains. They said Wright claims he put her body into a river after it fell out of his truck.
According to police, Wright has claimed the deaths were accidental.
Citing court documents, WJHL-TV reported that Wright told investigators he shot and killed Vanmeter after a fight. He claimed he was trying to shoot an animal when he shot the 17-year-old. And he told investigators that he shot Hopson after he tripped and fell.
Newman said Wright's claims are hard to believe. Autopsies were scheduled.
Wright has been charged with three counts of capital murder, for which the punishment can be death or life in prison without parole, said Barry L. Proctor, Wright's court-appointed attorney.
Proctor told The Associated Press that he's had one short meeting with Wright but cannot discuss the conversation. Proctor added that he hasn't seen a written summation of Wright's statements to police or video or audio of his conversations with them.
"We don't take a position quite yet on the statements that are there or whether they're truthful or not," Proctor said.
