A man and his son taking a walk Sunday afternoon in a wooded area off Five Palms Drive discovered partially buried human skeletal remains, officials said.
San Antonio Police Department homicide Sgt. Larry Ripley said they didn't know if the remains were of a male or female and there was no identification found early in the investigation.
The remains were found around 3 p.m. in the woods across from a residential neighborhood just off of Ray Ellison Drive.
Investigators would likely be processing the scene long into the night, Ripley added.
He said the remains were too large to be a child but didn't want to speculate further. Detectives will comb through missing person reports and the medical examiner's office also will be working to identify the remains.
