Sparks detectives are still looking for a man, wanted for questioning, in a murder on Sullivan Lane Sunday.
Investigators say they need the public's help finding Luis Puga.
Puga is believed to be with Victor Arzate, who's considered dangerous.
Today, Washoe County search and rescue teams combed Sullivan Lane and "I" Street, looking for shell casings from that shooting. Nineteen-year-old Juan Duenas was shot to death in what police say was a gang-related incident.
That brings the total to five gang-related murders since June.
Police also say more gangs are starting up here, compared to the mid-1990's when we saw an influx from California.
