Nationwide Sweep by U.S. Marshals Puts 345 Dangerous Sex Offenders Behind Bars

Washington – Today the U.S. Marshals Service concluded Operation Guardian, a three-year, national initiative specifically targeting the country’s most dangerous noncompliant sex offenders. Deputy marshals and law enforcement partners arrested 345 individuals who had failed to register with state authorities as required by law.

Marshals worked with state and local officials to identify specific non-registering fugitives based on their danger to the public and prior convictions for sex offenses. As of today, USMS investigators across the country have located 427 offenders of the 444 sought (or 96 percent of those targeted), including 82 individuals found outside the United States. These individuals represent more than 500 prior convictions for sexual offenses.

“The United States Marshals Service will not tolerate noncompliant and violent sex offenders who evade the law. The message we send to these individuals is there is nowhere you can hide,” said Director Stacia Hylton of the U.S. Marshals Service. “Operation Guardian enabled us to bring to bear the full weight of international, federal, state and local law enforcement resources and intelligence to locate the most egregious sex offenders—those who have victimized innocent children.”

District of New Hampshire, U.S. Marshal David Cargill, Jr. said “During this initiative in New Hampshire, we targeted one of the most dangerous types of sex offender, the ones who prey on our children. Cargill continued, “We are happy that we were able to take some of these offenders off of the streets, so all of our citizens can rest a little easier.”

The USMS assigns 129 criminal investigators to conduct sex offender, non-registrant investigations on a full-time basis. Operation Guardian was a collaborative effort led by the Marshals Service in cooperation with Interpol, the Diplomatic Security Service, Customs and Border Protection, and the National Center for Missing and Exploited Children.

“The National Center for Missing & Exploited Children is proud to partner with the U.S. Marshals in helping to protect our nation’s children,” said John Ryan, chief executive officer, NCMEC. “We applaud the overwhelming success of Operation Guardian which located hundreds of the country’s most dangerous noncompliant sex offenders.”

Among those arrested during Operation Guardian from the District of New Hampshire were:

  • On Oct. 10, 2010, fugitive sex offender, Timothy S. Lennox was arrested in Marlborough, Conn. Lennox was wanted in Seabrook, N.H. for failure to register as a sex offender. Lennox was originally convicted of a felonious sexual assault on a minor under the age of 15, which occurred in August, 1994. Lennox served a twelve month sentence for the felonious sexual assault and was required to register as a sex offender for life. Lennox initially registered in N.H., but then moved and did not notify the Seabrook, N.H. police department, or the New Hampshire State Sex Offender Registry as required by law. After a thorough investigation, Deputy marshals developed information that placed Lennox in Marlborough, Connecticut. Lennox was located and arrested by USMS investigators in Connecticut. Lennox was returned to New Hampshire, where he was convicted in U.S. District Court of violating the Adam Walsh Act. This conviction resulted in a Lennox receiving a 21 month federal sentence. Upon Lennox’s release from prison, he will be under the supervision of a Federal Probation Officer for five years, as well as his continued requirement to register as a sex offender for life.
  • On Oct 01, 2010, Felix Sanchez was arrested without incident in Humacao, Puerto Rico. Sanchez was wanted in the State of New Hampshire for failure to register as a sex offender. Sanchez’s original offense was for an indecent assault and battery on a child under the age of fourteen, which occurred in 1992. After Sanchez pled guilty to this offense in December, 1997, he was required to register as a convicted sex offender. During an investigation involving another criminal offense in Keene, N.H., it was learned that Sanchez was required to register as a sex offender and had not. In July, 2008 an arrest warrant was issued for Sanchez out of Keene, N.H. District Court, for failure to register as a sex offender. While conducting the investigation into the whereabouts of fugitive sex offender, Felix Sanchez, the U.S. Marshals Fugitive Task Force developed information indicating that Sanchez had moved to Puerto Rico. This information was passed on to our counterparts with the U.S. Marshals Fugitive Task Force in Puerto Rico, who quickly located and arrested Sanchez on 10/01/2010. Due to the location of the arrest, the District of New Hampshire agreed to transfer the case to the District of Puerto Rico for consideration for prosecution for Sanchez’s violations of the Adam Walsh Act.

The Behavioral Analysis Unit at the USMS National Sex Offender Targeting Center worked with the investigators to identify information related to the fugitives across a number of personal or social dimensions, including past sexual offending behavior. The prior convictions of the located offenders represent hundreds of victims and thousands of known sexual assaults. Most of the sexual assault events were engaged against children, and many involved extreme violence.

The National Center for Missing and Exploited Children estimates more than 700,000 sex offenders reside in the U.S. and that more than 100,000 are classified as noncompliant or unregistered.
Since its inception in 2006, the SOIB has planned and executed more than 900 sex offender compliance and enforcement operations. During these operations, the USMS partnered with more than 4,800 state and local law enforcement agencies to conduct more than 150,000 compliance checks.
