Gripping testimony in murder trial

Mar 3, 2014 - The Associated Press

CHEYENNE -- A woman who was wounded in a shooting that left two other people dead testified Friday that defendant Nathaniel Castellanos was the man who pulled the trigger each time.

Amber McGuire, called as a prosecution witness in Castellanos's trial, pointed to the 34-year-old defendant when she was asked who shot her and the others.

McGuire testified that she was "100 percent positive" that Castellanos was the shooter.

Castellanos is charged with two counts of first-degree murder and one count of attempted first-degree murder in the August 2011 shootings in Cheyenne.

If convicted, he could face the death penalty or life in prison.

Castellanos's lawyers maintain an unidentified person shot the three, not Castellanos.

Megan McIntosh, 25, and Corey Walker, 21, were killed.

McGuire said she and McIntosh were roommates and that Walker was McIntosh's boy-friend.

Earlier testimony indicated McIntosh and Castellanos once had a casual relationship.

McGuire said she, McIntosh, Walker and Castellanos had gone to a bar together on the night of the shooting and then to Castellanos' house.

She testified she arranged to get marijuana for Castellanos from someone else, and all four people left the house in a car to get it, but she became suspicious of Castellanos and called the deal off.

There was an argument in the car on the way back to Castellanos's house.

After they arrived, he didn't immediately go inside, but the others went to the kitchen-dining area on the upper floor, she said.

Castellanos then ran up the stairs and shot Walker, McGuire testified.

"He dropped to the floor," she said.

McIntosh immediately began to cry and tried to tell Castellanos to call 911, but Castellanos shouted at her and accused her of lying, McGuire said.

"How could you do this to me? Don't you love me?" McGuire quoted Castellanos as saying.

"It all happened so fast," McGuire said. "He was yelling, she was crying. After that, he shot Megan (McIntosh)."

"Then he shot me over here," McGuire said, pointing at her left cheek near her mouth. After she asked him why he did it, he shot her again, she said.
