A California teenager has been arrested for allegedly being involved in a triple-stabbing incident that left a mother and her daughter dead in their home in Rancho Cucamonga last month.
Jacob Allen Wright, 19, was arrested on Tuesday, April 13, after a five-week investigation into the murders of 44-year-old Jia Jai and her daughter, Ruby Meng, according to the San Bernardino County Sheriff's Department.
Detectives conducted a traffic stop on the suspect's vehicle and made the arrest. They also served a search warrant at his home, where they conducted an interview with Wright and gathered evidence, according to a press release.
Last month authorities revealed that neighborhood security footage showed a male subject close to the victims' home shortly after the murders.
The suspect reportedly attacked in a bedroom before fleeing through a back door. Two other family members were asleep in the home but were unharmed, Daily Bulletin reported.
A third stabbing victim, a 38-year-old woman who is believed to be a family friend, survived while the mother and daughter were found with stab wounds inside their home on the morning of March 7.
"You’d almost want to feel like it’s an inside job, or him knowing someone," a neighbor Sidney Stephens said, according to CBS Los Angeles. "It’s pretty scary to know that some random house is picked, you know. It could have been any of our houses."
Wright was arrested on charges of murder and attempted murder but a motive and connection with the victims has not yet been established, according to authorities. Authorities believe he acted alone. He is currently being held without bail at the West Valley Detention Center.
According to the Sheriff's Department, the FBI helped to assist in identifying Wright in connection with the incident.
Wright is reportedly due to appear at the Rancho Cucamonga Superior Court on Thursday, April 15.
