CLOVIS, N.M. - Investigators are looking at surveillance video and conducting interviews, but they have yet to identify any suspects in the killing of a 23-year-old woman whose body was found at a New Mexico park.
The woman's 6-year-old son was found unharmed in the parking lot, and what he told investigators has them considering the case as a homicide.
Police found the body of Ariel Ulibarri of Clovis on Sunday after people heard screams at the Goodwin Lake Trails Walking Park.
Police Capt. Patrick Whitney said investigators don't know whether the woman was targeted by somebody she knew or whether she was a victim of a random attack.
According to CBS affiliate KRQE there are anecdotal accounts that the victim was engaged to accused killer Ricardo Sena, and spoke out at his court hearing. Sena is awaiting trial for the stabbings of three people last year, including one who died, the station reports.
Police withheld specifics on how Ulibarri she was killed. They're waiting for the results of an autopsy by the state Office of the Medical Investigator, which said Tuesday that results likely won't be available for several weeks.
Meanwhile, police Sgt. Daron Roach said police patrol the park but have had few if any calls about trouble in the 40-acre park, which opened in 2011, the Clovis News Journal reported.
Parks Director Mark Dayhoff said the area around the trail gets little maintenance because it's intended to be a nature trail.
