Park rangers discovered human remains while they were performing trail maintenance in an unincorporated part of Morgan Hill on Friday, according to the Santa Clara County Sheriff's Office.
The rangers found bones in a shallow, dry ditch in the Uvas Canyon County Park at about 11:15 a.m., according to Santa Clara County sheriff's Sgt. Rick Sung.
Sung said the remains haven't been identified yet, but he doesn't believe they belong to Michelle Hoang Thi Le, 26, a nursing student who last seen at about 7 p.m. on May 27 at Kaiser Permanente Hayward Medical Center at 27303 Sleepy Hollow Ave.
"It's not that there isn't a chance they are from her," Sung said. "We're still looking into it."
He said it appears as though the remains may have appeared in the ditch recently, maybe in the past year. But there has been no direct evidence confirming when the remains were first in the ditch, Sung said.
Officials at the Santa Clara County medical examiner's office are assisting in the investigation
