Police used a GPS device Friday afternoon to track down a man suspected of brutally raping a woman a day earlier inside a restroom at Kewin Park in Modesto's La Loma neighborhood.
Adam Edward Grider, 30, of Modesto was arrested on suspicion of rape, assault with a deadly weapon and violating parole. He was being held at the Stanislaus County Jail on Saturday, with bail set at $150,000.
Using the GPS device, investigators also determined that Grider was at the park in the area of the restroom when the attack occurred Thursday afternoon, said police Lt. Jolene Gonzales.
The 23-year-old woman was walking through the park and went into a restroom. Minutes later, Grider followed the woman inside.
Never miss a local story.
Gonzales said Grider brandished a knife and raped the woman inside the restroom. The woman then went home. She told police she didn't report the attack because she feared for her life and the safety of her family.
The woman was experiencing some bleeding Friday afternoon and went to a local hospital to seek treatment.
About 2:15 p.m. Friday, Modesto police officer Mike Callahan received a report of the sexual assault and went to the hospital to speak to the victim. Gonzales said the victim told Callahan she recognized Grider as an acquaintance she had not seen in three years.
The victim was shown a photo lineup and identified Grider as her attacker, Gonzales said. Police discovered that Grider was on parole and was listed on the Megan's law Web site. State law requires the home addresses of convicted sex offenders to be listed on the site.
Officers contacted parole agents, who helped police find Grider by using the GPS tracking device strapped to his ankle, a requirement of his parole.
Gonzales said the parole agents led officers directly to Grider, who was found about 4 p.m. outside a fast food restaurant at Standiford Avenue and Tully Road in north Modesto. He was taken into custody without incident.
