"They killed Anniversary..."

A miniature horse given to a boy with brain cancer by the Make-A-Wish Foundation was killed by a pair of pit bulls who were found roaming in his yard, authorities said.

The 31-inch tall horse, Anniversary, was donated by the foundation to 3-year-old Christian Vasquez in late August.

Christian, who was diagnosed in January with a malignant form of brain cancer, received a pull cart, a blanket, a halter and a bridle set from the foundation on Saturday, said Jelaine Workman, executive director for the foundation's Amarillo chapter.

Two days later, Anniversary was found dead on his property in Pampa by Christian's father, Raul Vasquez.

The father was nearly attacked by the dogs but managed to climb a tree and call 911 on his cell phone. "I was scared to death," said Raul Vasquez, 41. "They killed Anniversary, and I thought they would kill me too."

It was unclear how the dogs entered the property, which is surrounded by a 4 1/2-foot-high fence.
