() The FBI and local law enforcement agents will be taking a fresh look at the 15-year-old missing case of Kyron Horman, who vanished from a Portland elementary school when he was 7 years old.

The review comes after an effort to digitize the old case files and will include input from the FBI’s Behavioral Analysis Unit.

The original detectives on Kyron’s case have retired, and there has been little new information about the case.

Mother believes former stepmother is involved in son’s disappearance

New Multnomah County, Oregon, District Attorney Nathan Vasquez has ordered a thorough, methodical review of the case. His office has not provided a timeframe for the review.

Kyron’s mother, Desiree Young, has pressured officials to continue looking into the case and believes her son’s former stepmother, Terri Mouton Horman, is involved in his disappearance.

On the morning Kyron disappeared, Horman had driven him to school and said she saw him walking down the hall toward his classroom at around 8:45 a.m.

But at 10 a.m., Kyron’s teacher marked him absent because he never made it to class.

When Kyron didn’t get off the bus that afternoon at 3:30 p.m., Horman and Kyron’s father, Kaine Horman, went to the school to find him, where a school secretary called 911 to report him missing.

Landscaper claims stepmother offered money to kill boy’s father

A weekslong search effort with hundreds of people involved did not turn up any information on what might have happened to Kyron. Authorities did not identify Terri Horman as a suspect but did question her friends and released fliers with her picture on them. Kaine Horman filed for divorce less than a month after his son vanished.

A landscaper who worked for the couple told authorities that Terri Horman had approached him months earlier and offered to pay him to kill her husband, a claim she denied.

Terri Horman has denied involvement with Kyron’s disappearance, though Young has publicly accused her of being involved.

Stepmother goes on Dr. Phil, claims man in truck kidnapped Kyron Horman

Years after Kyron’s disappearance, Terri Horman went on “Dr. Phil” and said she thought a man in a white pickup truck kidnapped Kyron.

Kaine Horman said his then-wife vented to family and friends about her results on a polygraph exam done during the investigation.

There is a $50,000 reward being offered for information that leads to the resolution of the case. Anyone with information can call the MCSO Tipline at 503-988-0560, email MCSOTipLine@mcso.us or contact the National Center for Missing and Exploited Children Tip Line at 1-800-THE-LOST.
