Seven-year-old Karla was last seen at approximately 7:00 p.m. on October 20, 1999 in the 800 block of Bonita Avenue in Las Vegas, Nevada. She went to visit a neighbor's son to play with him, but the neighbor told her to go home because it was getting late.
Karla played outside alone for about fifteen minutes before leaving on her bike. The location was two blocks from her family's home and also near the Stratosphere Tower in downtown Las Vegas. She never returned to her house and has not been seen again.
Karla wasn't reported missing until the next morning. Her father spoke to the neighbor who saw Karla, assumed she must have gone to another friend's house, and went home to bed.
The next morning, when Karla still wasn't home, her mother called the school to see if she'd gone there for classes and the school principal called the police at this time.
Karla's disappearance was originally thought to be linked to a debt her parents owed a former brother-in-law.
A few months before Karla disappeared, the brother-in-law came to Las Vegas and demanded to be repaid. The family gave him $1,000, but he said that was only the interest and he wanted more money. It was theorized that the man abducted Karla in attempt to extort money from her parents, but he has since been ruled out as a suspect in her case.
Investigators now believe Karla was taken by someone outside her family. As of 2018, her disappearance remains unsolved.
Karla is described as a Hispanic female with black hair, brown eyes, is 3'5 and weighs 49 pounds. She has moles above her right eyebrow and on her lower lip near the right corner of her mouth; her teeth are unevenly spaced with wide gaps between them which have visible cavities. She has also a surgical scar on her abdomen.
Karla was last seen wearing a black jacket, a blue & white striped shirt & red pants, and her fingernails were painted green. She speaks Spanish and limited English. She also has an unspecified medical condition and may be need of medical attention.
