Kyron Horman has been missing since June 4, 2010, but his mother is not giving up.

Kyron disappeared on June 4, 2010. He was last seen by his stepmother, who said she dropped off the 7-year-old at his elementary school in Portland.

For years, volunteers, search dogs and relatives have combed through neighborhoods, searching for clues.

The Multnomah County Sheriff’s Office reiterated that the investigation is ongoing this year. It’s offering $50,000 for information that will help resolve the case.

“A full time sheriff’s office detective is primarily assigned to the Kyron Horman missing child investigation, and efforts to locate Kyron,” the office said in a statement. It has also commissioned a retired FBI agent who specializes in child abduction to help with the case.

Kyron Horman was 7 years old when he went missing.

Kyron was 7 years old when he went missing. He was last seen by his stepmother, Terri Horman, who told police she had dropped him off at his school, Skyline Elementary.

Since Kyron’s disappearance, most of the speculation has focused on the boy’s stepmother.

In August 2010, investigators solicited the public’s help for information about the location of the white pickup truck that she is believed to have driven the morning of Kyron’s disappearance.

And in divorce filings, the boy’s father, Kaine Horman, said he believes his estranged wife, Terri Horman, “is involved” in the boy’s disappearance.

No charges have been filed against anyone in the case, nor has anyone officially been named a suspect.
