LAS VEGAS -- Police are still on the hunt for a group of people responsible for a rash of violent robberies early Wednesday morning. But as those suspects remain on the loose, some residents in the area where those crimes happened are growing concerned.

Residents want the group responsible for the robberies to see justice, but their biggest worry is getting them off the streets. People who frequent the bus stops and live in the neighborhoods where the crime happened, say they are on edge.

"I'm looking over my shoulder a lot and making sure that nobody is trying to walk up on me," said resident Matika Hogan.

"How can you protect yourself against that? You walk down the street and here comes a car and then somebody with a gun. What can you do," said resident James Moniz.

Detectives are still following up on several leads they've received since the string of crimes happened.

LAS VEGAS -- A Las Vegas high school teacher is dead after a crime spree that happened early Wednesday morning. Police say the suspects were looking for crimes of opportunity when they violently robbed several people, including the teacher and a homeless person.

Students from Eldorado High School say there is a sense of sadness in the halls now that science teacher Timothy VanDerbosch is dead.

"How can you do something like that? You don't know the person, but people don't think that way, you know. People who would do something like that wouldn't think like that," said student Melissa Valenzuala.

Police say the group responsible for the crimes brutally beat VanDerbosch before he ran to get away and was hit by a passing car. He was transported to the hospital where he later died.

LAS VEGAS -- Lawmakers are currently looking at toughening up on DUI laws. State officials and lawmakers are planning to file bill drafts for the 2011 state legislative session that would put tougher restrictions on drunk drivers.

For Joan Eddowes, DUI is personal. She lost her 17-year-old son, Mark, to a drunk driver back in 1991.

"Just slammed into my son, who was on a bicycle coming home from work, and literally just tore his body to pieces," she said.

The accident happened only two weeks before his high school graduation.

"You never think its going to happen to you. You never think you are going to be put in that position," she said.

For nearly two decades, Eddowes has been a DUI advocate and supports tougher laws against DUI. That's something lawmakers are currently looking at drafting bills for upcoming legislation.

"Whatever they come up with, it can only help. It can't hurt," she said.
