Portland, OR -

Authorities in Oregon say text messages found hours before the discovery of a college student's body on a heavily-wooded hill were the first indication he planned to kill himself.

Johnathan Croom was found just 1,000 yards from the vehicle he abandoned near Riddle, Ore.

Douglas County sheriff's spokesman Dwes Hutson says crews searching the area for days after Croom's vehicle was found were looking for a live person.

The discovery of the texts changed the nature of the search.

Hutson says crews brought in dogs used to find cadavers, and found Croom's body within hours.

The Mesa, Ariz., college student was scheduled to drive home from Seattle and was due back Aug. 17.

Croom's father said Monday night his son was grieving the end of a recent relationship.
