UPDATE – Featured Most Wanted Fugitive Arrested in Oregon

AUSTIN, TX  –  Donald Jack Robertson II, 43, a Texas 10 Most Wanted Fugitive and November’s featured fugitive, is now in custody after being captured on Nov. 23 in Portland, Oregon.

Robertson had been wanted since 2011 for aggravated sexual assault of a child, sexual assault of a child and indecency with a child-sexual contact.  The arrest was the result of tip information, and a reward up to $10,000 will be paid.

Working off tip information, the U.S. Marshals Joint East Texas Fugitive Task Force coordinated with the U.S. Marshals Service-District of Oregon to locate and arrest Robertson at a residence in Portland.  Since the arrest was the result of tip information and the tip was received during the month that Robertson was featured, the increased reward of up to $10,000 (originally $5,000) will be paid.

For more information, see his captured bulletin at: http://www.dps.texas.gov/Texas10MostW…/capturedDetails.aspx….

So far in 2015, DPS and other agencies have arrested 28 Texas 10 Most Wanted Fugitives and Sex Offenders, including 19 sex offenders, and $79,000 in rewards have been paid for tips that resulted in arrests.

One offender from the Texas 10 Most Wanted Program is featured each month in hopes the higher reward money from the Governor’s Criminal Justice Division will generate additional tips.
