Palo Alto police arrested on Thursday morning the sister-in-law of a Palo Alto woman who was found stabbed to death in her Creekside Drive home in July, the police department announced.
Jingyan Jin, 41, of Palo Alto, was arrested for the homicide of Jenny Shi, 65. Police received a call at 7:42 p.m. on July 7 from a family member (not Jin) regarding a suspicious circumstance at a home in the 300 block of Creekside. Officers found Shi dead inside. The family member had gone to the Greenmeadow neighborhood home to check on Shi after failing to reach the victim, police said at the time.
An autopsy by the Santa Clara County Medical Examiner-Coroner determined that Shi had been stabbed multiple times, according to the coroner.
Crime scene investigators located evidence at the home, which was later processed by the Santa Clara County District Attorney’s Crime Laboratory, that indicated probable cause to arrest Jin for Shi's death, police said.
Detectives presented the evidence to the Santa Clara County District Attorney’s Office and obtained a probable cause warrant for Jin's arrest. She was taken into custody without incident at her home in the 700 block of San Antonio Road in Palo Alto at about 8:04 a.m. Thursday, police said. Detectives and crime scene personnel then served a search warrant at her home.
"Despite the arrest, the investigation remains ongoing as detectives work through a significant amount of evidence," police said in a statement. "While police are not ruling out the possibility of additional suspects being involved, there currently is no evidence to suggest that. No further details will be released at this time, including any speculation on a possible motive."
A neighbor said after the homicide that Shi's sister-in-law had lived with her but had moved out the year before. They apparently did not get along, the neighbor said.
Jin remains in custody. Formal charges have not yet been filed by the Santa Clara County District Attorney's Office, according to the court's clerk. She is scheduled to appear in Palo Alto's courthouse on Oct. 11.
