A 99-year-old woman was in for a little more than a rude awakening when a gunman entered her house and kept her hostage.

Doris Rucker Wasden, from West Valley City, Utah, was fast asleep when someone entered her house after shooting into a sliding glass door, the Deseret News reported.

The culprit was 18-year-old Freddy Velasquez, who first encountered Wasden's granddaughter CJ Montoya and her fiance, Jim Gabbard.

They soon came face-to-face with Velasquez who told Gabbard: "Give me your car keys or I'm going to kill you," local news station KSL reports.

While the pair managed to escape from the teenager at about 1:45 a.m., Wasden was still trapped in the house with the armed intruder.

Wasden told Fox 13 that Velasquez yanked out of her bed and left her on her bum, but when he returned, she had already crawled back in.

"He tried to talk to me, but I said, 'I can't hear you. I can't hear you.' Then he realized I was a very old woman, so he was pretty nice to me after that," Wasden said.

Despite spending hours negotiating with the police, it wasn't until Wasden started giving Velasquez a lecture on making a mess that he felt prompted to release her.

"He was riffling through her drawers, making a mess, spilling things all over and she has her 100th birthday party one week from today," Gabbard said. "And her words to him were, 'I just had this house cleaned for my party and you're messing it up. You better knock it off.'"

Velasquez wouldn't be captured until 5:20 a.m., when he tried to flee with a car parked inside. However, authorities blocked the garage door and he was swiftly arrested.

He was charged with six felonies, including aggravated assault, aggravated burglary, aggravated kidnapping, aggravated robbery, felony discharge of a firearm and receiving or transferring a stolen vehicle.

Despite the harrowing ordeal, the family doesn't hold any resentment towards Velasquez, and plan on celebrating Wasden's birthday next Saturday, all according to plan.

"Grandma's disposition is what she's taught us: that you can't have animosity and you can't be angry with the young man," Gabbard said. "He made a mistake and we don't hold resentment, and we just hope that he gets some help and hope that his family is okay."
