Singh was a 33-year-old Fiji native who had been with the Newman Police Department since 2011. Sheriff's officials said he initiated the traffic stop for suspected drunk-driving at 12:57 a.m. and reported "shots fired" over the radio moments later. He was found at the scene with gunshot wounds and died at a hospital.
The suspect, later identified by police as 32-year-old Gustavo Perez Arriaga, fled the area and law enforcement didn't know where he went. The California Highway Patrol issued a "blue alert" in five counties, including Santa Clara, and law enforcement began a statewide effort to locate Arriaga.
"We have spared no expense, we will relentlessly continue to hunt our suspect down and bring him to justice," Sheriff Adam Christianson of Stanislaus County said on Dec. 27.
At about 4 p.m. that day, Christianson contacted Kern County Sheriff Donny Youngblood to notify him the suspect was believed to be between Modesto and Bakersfield, headed toward Mexico.
Deputies in Kern County began watching for Arriaga and located him at a home in the 8200 block of Brooks Road near the unincorporated town of Lamont early last Friday morning. After officers served a warrant and a SWAT team arrived, Arriaga emerged from the house with his hands in the air and surrendered himself to deputies, Youngblood said.
Three other Bakersfield residents at the house were arrested on suspicion of aiding and abetting: Bernabe Madrigal Castaneda, 59, Erasmo Villegas, 36, Maria Luisa Moreno, 57.
Authorities also confirmed Friday that 34-year-old Chowchilla resident Conrado Virgen Mendoza, identified as Arriaga's brother, was arrested in Livermore on suspicion of aiding his brother's efforts to elude police. Details about Mendoza's arrest in the Tri-Valley were not released.
Detectives also arrested Arriaga's girlfriend, Ana Leyde Cervantes, 30, in Turlock on suspicion of aiding and abetting, and two other men, 25-year-old Adrian Virgen and 27-year-old Erik Razo Quiroz, were arrested on suspicion of being accessories to a felony.
According to Newman police, Arriaga was residing in the United States illegally. Youngblood said Arriaga's status still needs to be confirmed, and the loss of a police officer's life is the priority in this case.
"His immigration status is secondary, however it's extremely important that we get there and confirm whether the person had a right to be in this country or not," Youngblood said.
President Donald Trump leveraged the killing to promote his border wall plan last week, tweeting, "There is right now a full scale manhunt going on in California for an illegal immigrant accused of shooting and killing a police officer during a traffic stop. Time to get tough on Border Security. Build the Wall!"
Youngblood emphasized his opposition was to sanctuary county laws that limit deputies from sharing information with federal authorities and said law enforcement in California have an extremely good network of communication.
"When you use a firearm against a police officer, you can run but you can't hide," Youngblood said. "When you attack someone who's doing an honorable profession, no stone goes unturned."
The Stanislaus County deputy sheriff's union has created an official donation page at https://bit.ly/2LDVO6z to raise money for Singh's family.
Singh had been on track to lead the Police Department one day, Newman Police Chief Randy Richardson said, and was a proud officer who did everything he could to improve at his job.
"He was a police officer, but more importantly he was a human being, and that's how he would want to be remembered," Richardson said.

The Alameda County Coroner's Bureau last Friday confirmed the identity of the transient man who died after being hit by a BART train on the tracks between the Castro Valley and West Dublin-Pleasanton stations last month.
Victor Hernandez Cardenas, 37, succumbed at the scene to multiple blunt injuries after being struck while around the tracks at about 11:15 a.m. Dec. 10, according to authorities.
Coroner's officials reported having difficulty locating next of kin for Hernandez Cardenas to notify, a required step before a fatal victim's identity is released to the public.
BART police have not confirmed why the man was on the BART tracks or how he gained access that morning.
"Police are classifying this as an 'unattended death' and believe the decedent entered the BART right-of-way of his own volition," BART spokesman Jim Allison said on Friday, explaining that "unattended death" is police terminology for a case when a person is alone when they died. "No further information is available."
