Feliciano Valencia-Santiago, 47, was arrested at about 7:50 p.m. Friday as he was riding a bicycle in the area of El Camino Real and Halford Avenue in Santa Clara. Detectives tracked him down after receiving numerous leads.
Orozco's body was found on June 5 in a large, loosely cinched garbage bag near some bushes in the 800 block of Ticonderoga Drive, according to the Sunnyvale Department of Public Safety.
Detectives believe Orozco, a 46-year-old San Jose resident, was murdered in a house in the 800 block of Revere Drive in Sunnyvale, less than a mile from where her body was found. The house has been vacant since a fire broke out there in December, police said.
The Santa Clara County medical examiner's office determined that the cause of Orozco's death was trauma to the head.
Valencia-Santiago was booked into Santa Clara County Jail on a homicide charge.
The California Department of Justice assisted in the investigation.
