High school guidance counselor charged with sexual offenses against 2 women he met through Tinder

Police have arrested a Montgomery County high school guidance counselor for sexual offenses committed on two women he met through the Tinder app.

Montgomery County police have charged 33-year-old Colin Sime Black with two counts of second-degree sexual offense and one count of second-degree assault.

According to police, a woman reported on March 24 that she met Black through the app and agreed to meet him at his apartment in Rockville. The two engaged in consensual sex, but Black then committed sexual acts without the victim's consent.

In September, police were informed of another possible sexual assault that took place in Dec. 2016 involving Black. Another woman told investigators that she also met Black through Tinder last year. On Dec. 31, they met for a second time and engaged in consensual sex. However, Black also committed sexual acts without the consent of the woman, police say.

"Neither one of these victims knew about the other, and so investigators then brought this case forward and arrested him earlier today," said Montgomery County Police Capt. Paul Starks.

Black has worked as a guidance counselor at Albert Einstein High School in Kensington since 2009. Montgomery County Public Schools says he has been placed on leave.

Einstein High School principal James Fernandez sent a home a letter to parents saying:

Dear Parents and Guardians:

I am writing to inform you of the arrest of Mr. Colin Black, a counselor at Albert Einstein High School, on charges of second degree assault and second degree sexual offense.The alleged offenses did not occur on Montgomery County Public Schools (MCPS) property, are not related to any MCPS students, and do not involve any minors.

MCPS has just learned of this investigation and is fully cooperating with the Montgomery County Police Department (MCPD) and the Montgomery County State's Attorney's Office on this matter.

Mr. Black has been employed with MCPS since 2009. In addition to his role as a counselor, Mr. Black has previously served as a coach at Einstein and a substitute teacher with MCPS.

These charges are deeply troubling. This type of behavior does not reflect the principles of MCPS or our community, and it will not be tolerated.

As always, the safety and security of our students is our top priority.
