Illegal immigrant accused of murdering four in Nevada came to the US from El Salvador, says ICE

U.S. immigration authorities say a man suspected of killing four people in Nevada over the last few weeks is from El Salvador and entered the United States illegally.

Murder suspect Wilbur Martinez-Guzman, 19, had no criminal record or history of previous immigration violations, Immigration and Customs Enforcement said on Tuesday.

The agency did not have additional details on his alleged illegal entry to the U.S., including when and where it occurred. The agency's public affairs staff is furloughed because of the government shutdown.

The case shot to national prominence on Monday after President Donald Trumptweeted about the killings to support his case for the proposed border wall withMexico.

Martinez-Guzman has been linked to the murders of four people in the Carson City area.

Investigators have not revealed a motive in the case.
