A man suspected of living in the US illegally shot and killed four people in Nevada this month, officials said.

Wilbur Martinez-Guzman was arrested Saturday in Carson City for possession of stolen property, burglary and immigration infractions — but authorities expect to file murder charges against him in the coming days.

“At this stage in the investigation, we feel confident we have the evidence that will link him to all four homicides,” Washoe County Sheriff Darin Balaam told reporters during a press conference on Sunday.

The 19-year-old, who’s lived in the area for about a year, is suspected in the shooting deaths of an elderly couple in Reno and two women in Gardnerville Ranchos.

President Trump chimed in on the case Monday, using the string of homicides as a reason for his proposed border wall.

“Four people in Nevada viciously robbed and killed by an illegal immigrant who should not have been in our Country,” Trump tweeted. “We need a powerful Wall!”

It’s unclear where Martinez-Guzman is originally from or how long he’s been in the US.
