Police Hope Surveillance Video Will Offer Clues About Missing Missouri Teen

Missouri police hope that releasing a surveillance video will offer clues about a teenage girl's disappearance more than a month ago.

Kara Kopetsky, 17, vanished early in May from her hometown of Belton, Mo., which is only about six miles from where the body of 18-year-old Kelsey Smith was found last week.

The newly released video shows Kara at her high school the morning of May 2, the last time she was seen.

Kara's mother, Rhonda Beckford, said her daughter had called that morning to ask her to bring her history textbook to school and wash her work uniform. But the teen never arrived at work that afternoon.

Though the last confirmed sighting of Kara was at her high school, there were also reports that she was spotted two days later on May 4 at an area gas station in Lewisburg, Mo., on the same day her cell phone and debit card were last used.

Smith was abducted from a Target store parking lot in Overland Park, Ill. Edwin R. Hall, 26, was arrested and charged last week with her kidnapping and murder.

"We're convinced someone knows something. [Hall] was from Olathe, which is as close as Overland Park. You know, it's 20 minutes [away]," Beckford told FOX News last week, implying that Hall could be involved in her daughter's disappearance.

Belton police said they were not ruling out a connection between Kara's disappearance and Smith's murder.

"I’m not going to discount the possibility these cases are connected … but I can’t draw that conclusion at this point," Overland Park Police Chief John Douglass told reporters last week.

Beckford said Kara had an ex-boyfriend whom police had interviewed several times, and he has been cooperating fully.

Kara is 5 feet, 6 inches tall, weighs 115 pounds and has red hair and hazel eyes.
