Charges: Police officer had decade-long relationship with minor

SEATTLE -- A former sergeant with the Monroe Police Department has been charged with abusing his position of authority to enter into a decade-long sexual relationship with a 14-year-old girl.

According to the Washington State Patrol, 58-year-old Carlos Martinez, who left the Monroe Police Department in 2009, used his position as an officer to isolate and manipulate the victim, who is now 24.

He reportedly photographed the victim using the bathroom without her knowledge and continued to photograph her in sexually explicit conduct as their relationship developed.

"He groomed and victimized a very young girl, engaged in a sexual relationship that spanned 10 years," said Lt. Ron Mead with the Washington State Patrol.

As a Monroe police officer. Martinez often worked with young kids in the DARE program. The police chief says Martinez came under investigation for domestic violence against his wife in 2009, and when he learned he'd be disciplined, Martinez quit.

The case broke open after Martinez left his Monroe home and went to Texas to continue serving as a helicopter pilot in the Army. Texas investigators found explicit images of minors on his computer, and believe he may have exploited other children as well.

"We have reason to believe that there are additional victims," Mead said.

Investigators are reaching out to other potential victims, and have interviewed some already, so more charges could be added to this case. As it stands now, the Snohomish County Prosecutor has charged Martinez with child molestation, voyeurism and sexual exploitation of a minor. All three charges are felonies.

His next court appearance is scheduled for Aug. 6.
