NORTH LAS VEGAS, Nev. -- Some North Las Vegas residents say they feel like prisoners in their own homes after four murders in only a matter of days.

The murders have happened over the span of about a week. Over the weekend there was also a stabbing and a shooting at a wake. Neighbors say the violence has to stop.

"It's a pretty tragic thing to experience -- especially so close," said resident Tony Lowe. "We don't like to seem unfriendly to people, but it does make you a whole lot more cautious about where you go and when you go."

Police have arrested one suspect in one of the murders. As for the others though, those suspects are still on the run.

NORTH LAS VEGAS, Nev. -- North Las Vegas has not had a murder since July, and then in one 24-hour period over the weekend, three people were killed in three separate incidents.

A gunman looking for cash shot a man who was fixing a car in front of a North Las Vegas home. Now a family is making a plea to the community to help catch the killer of the father of two teenaged sons.

Two men were fixing a car -- one of them was mechanic 44-year-old Darren Rael, hired through Craigslist. He was shot and killed and another man was nearly killed, except the shooter's gun jammed.

"Think of how you would feel if you had to watch on TV that your brother, your son, your dad, your nephew, anybody wasn't coming home. That you're never going to see them walk through the door, never get a phone call. Think of how you would feel if it affected your family. Do the right thing if you know anything," said Rael's sister Nicole Sena.

LAS VEGAS -- A high school student is in jail after bringing a loaded gun to school. Now he faces expulsion and felony charges.

Classes at Mojave High School were never disrupted by the incident because it happened before the morning bell rang.

School police say 18-year-old senior Jamar Holman arrived with other students around 6:45 a.m. Officers say they noticed him acting strangely and approached him. They said his odd behavior continued, so they took him inside and searched his backpack. That's when they found a loaded .38 caliber stolen handgun.
