HENRYETTA, Okla. (NewsNation) — A woman identified four of the seven bodies found dead at a rural Oklahoma property as her daughter and three grandchildren on Tuesday.

Authorities discovered the bodies of seven people Monday while searching a rural Oklahoma property for two missing teenagers: 14-year-old Ivy Webster and 16-year-old Brittany Brewer.

Janette Mayo, 59, of Westville, Oklahoma, said the Okmulgee County Sheriff’s Office notified her late Monday that the other four victims were her daughter, Holly Guess, 35, and her grandchildren, Rylee Elizabeth Allen, 17, Michael James Mayo, 15, and Tiffany Dore Guess, 13.

The bodies were found near the town of Henryetta, a town of about 6,000 located about 90 miles east of Oklahoma City, Oklahoma State Bureau of Investigation spokesman Gerald Davidson said.

“We’ve had our share of troubles and woes, but this one is pretty bad,” Okmulgee County Sheriff Eddy Rice told reporters.

Rice said Monday that the state medical examiner would have to confirm the identities of the victims, but, “We believe that we have found the persons.” He said Monday that the bodies were believed to include those of Webster and Brewer, along with Jesse McFadden, the felon authorities had said the teens were traveling with.

“We are no longer looking,” Rice said. “We believe to have found everything that we were seeking this morning. Our hearts go out to the families and friends, schoolmates and everyone else.”

While Rice declined to provide details of how they died, the tragedy comes in a year marked by an uptick in mass killings in the United States.

Mayo said the Sheriff’s Office told her that her daughter and grandchildren were all found shot to death in various locations on McFadden’s property.
