Major update in kidnapping case as new surveillance video captures moment entire family and baby forced out at gunpoint

SURVEILLANCE video captured the horrifying moment an entire family was kidnapped at gunpoint - and they have not been seen since.

The footage shows married couple Jasleen Kaur, 27, and Jasdeep Singh, 36, their eight-month-old baby Aroohi Dheri, and Jasdeep's brother Amandeep Singh, 39, being walked out of a business in Northern California at gunpoint on Monday.

The kidnapper, who was carrying a gun, wore a medical mask over his face as he escorted them from the business off South Highway 59, into a waiting car.

Both Singh brothers appeared to have their hands zip tied behind their backs as they were forced into the vehicle while Kaur was allowed to carry her child.

None of the family have been seen since the kidnapping.

Police have since taken suspect Jesus Manuel Salgado into custody.

The 48-year-old had attempted to take his own life "prior to law enforcement involvement," cops said.

He is currently in critical condition receiving medical attention, the Merced County Sheriff's Office said in a Facebook post.

Detectives took Salgado into custody after the sheriff's office received information on Tuesday "that one of the victim’s ATM cards was used at an ATM located at a bank in the City of Atwater."

On Wednesday, police released surveillance footage of the kidnapping.

The suspect first enters the building at just before 9am after walking up the property's walkway with a white trash bag in his hand.

The business that has no cameras inside.

"At 9.11am, the back door opens," a deputy said at a press conference.

The two brothers walk backwards, arms tied behind their backs, followed by the suspect with a gun.

They are escorted to the vehicle parked nearby.

The suspect then returns to the business and comes out with Kaur, who is holding Aroohi Dheri.

"At this time, the four family members remain missing and the sheriff's office said authorities are not aware of any motive.

"Investigators continue to follow up on all leads and are working diligently to find the family," the agency said.

"We continue to ask for the public’s help with any information that may assist us in locating the family’s whereabouts."

Amandeep Singh's truck was found on fire around noon on Monday, the sheriff's office said.

When police went to his home around 12.35 pm on Monday, they couldn't find him but the sheriff's office said they did speak to another relative.

That relative reported the family members missing when they couldn't contact Jasleen Kaur, Jasdeep Singh, or Amandeep Singh.

The sheriff said the investigation into their kidnapping began about an hour after patrol staff reported to the store on Highway 59.

"Through investigative leads, [patrol staff] brought detectives in and they were able to determine that a kidnapping had, in fact, occurred."
