HAPPY, Texas -- A tornado swept through a western Texas town Sunday night, killing at least four people and injuring others.
Several people were missing, said Mary Lenz, spokeswoman for the State Division of Emergency Management.
Twenty homes were heavily damaged along Interstate 27 in Happy, a small town about 30 miles south of Amarillo.
At least four people were injured, city secretary Patricia Simms said.
Tonya Smith and her husband were driving toward Happy when they saw the tornado form.
"We thought it was just a really big dust devil. It was right beside us. We stopped and watched it until we realized what it was," she said.
The tornado was one of at least six reported in the state Sunday.
