HENDERSON, Nev. -- A woman who police said used her children as hostages during a routine traffic stop has died after being shot by an officer, Las Vegas station KVVU is reporting.

Deshira Selimaj, 42, died at St. Rose-Siena hospital after the Tuesday afternoon shooting near Sunridge Heights and Pecos Ridge parkways.

Police spokesman Todd Rasmussen said a confrontation ensued after the woman's husband, 65-year-old Zyber Selimaj, was stopped in another ice cream truck.

Shortly after police pulled over Zyber Selimaj, Deshira Selimaj arrived in another ice cream truck with her 7- and 11-year-old sons, police said. She then began to wield a knife and at one point, police said she used one of the children as a shield.

Officers tried to stun the woman with a Taser but failed. When she made an aggressive move, an officer shot her.

Zyber Selimaj was arrested and is in the Henderson city jail. The children were taken to Child Haven.

The officer has been put on paid administrative leave while department officials investigate.
