A California sheriff says the suspect in the shooting death of a police officer is in United States illegally.

Stanislaus County Sheriff Adam Christianson told reporters Thursday that authorities have identified a suspect but didn’t name him. Authorities are still searching for the attacker.

Christianson’s agency is leading the investigation into the slaying of Cpl. Ronil Singh of the small-town Newman Police Department.

The sheriff says Singh pulled over the attacker as part of a DUI investigation Wednesday and that the officer fired back to try to defend himself.

President Trump called for action of suspect manhunt and building the border wall.

‘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,’ Trump tweeted.

‘Time to get tough on Border Security. Build the Wall!’

Newman police said Thursday evening that detectives performed a search warrant at a property in El Nido of Merced County, but had no luck.

‘The suspect was not located at the property and the investigation remains fluid. We will have no details at this time regarding the search warrant,’ the department said.

Christianson said the suspect ‘doesn’t belong here’ and that ‘he is a criminal’.

A ground and air search began. Authorities were looking for a man seen in surveillance photos at a convenience store shortly before the shooting.

He appeared to be a heavy man with short, dark hair, a silver chain, jeans, dark T-shirt and a dark jacket with white Ecko brand patches on the shoulders.

Singh was shot a few minutes after radioing in that he was pulling over a gray pickup truck that had no license plate in Newman, a town of about 10,000 people some 100 miles (160 kilometers) southeast of San Francisco.

Singh was pronounced dead at a hospital.

“He was living the American dream,” said Stanislaus County sheriff’s Deputy Royjinder Singh, who is not related to the slain officer but knew him.

“He loved camping, loved hunting, loved fishing, loved his family,” the deputy said.
