Neighbors are nervous in northern Nevada, where four people were killed this month in slayings that officials blame on a 19-year-old from El Salvador said to be in the U.S. illegally.
Authorities in Nevada and President Donald Trump in Washington are blaming the four killings over a six-day span on Wilbur Ernesto Martinez-Guzman, who was arrested Saturday in Carson City.
On Thursday, Martinez-Guzman is due in a Carson City court on property crime charges alleging he sold victims' property at pawn shops.
Prosecutors in Douglas and Washoe counties, where the victims lived, say they're preparing to file murder charges in coming days.
The victims' neighbors have boosted security around their homes with new alarms, floodlights and cameras.
