A Jetson Center for Youth social worker was arrested Thursday and is accused of having sex with a 20-year-old inmate assigned to the juvenile detention facility in Baker.

The relationship began during Lashonda Lang’s employment with the Office of Juvenile Justice, an arrest warrant says.

Lang, 39, was hired in December 2009, the warrant says. She was fired in November.

A month before her termination, Jetson Director Deron Brown started looking into complaints about Lang regarding her behavior with a man she was counseling at the youth prison, the warrant says.

One complainant told Brown that Lang was spending a lot of time with the man, more than what a social worker should spend with a client, the warrant says.

Another complainant told Brown that Lang was seen sitting close to the man and that their behavior “resembled that of a couple dating, rather than a professional relationship.”

Brown also was told that Lang was seen dressed inappropriately during a visit with the man, the warrant says.

Letters Lang wrote to the man after he was transferred to Bridge City Center for Youth bolstered the validity of those complaints, the warrant adds.

“I really hope that you enjoyed your Escort on yesterday,” one of the letters reads.

“I am head over heels in love with you,” another letter says.

Lang also writes that she knows she is risking her job by being in a sexual relationship with the man, the warrant says.

Brown referred the letters to an investigator with the Office of Juvenile Justice. A warrant for Lang’s arrest was issued in January.

Baton Rouge police arrested Lang on Wednesday during a traffic stop in the 600 block of North 28th Street, police spokesman Cpl. L’Jean McKneely said.

Lang, 6415 E. Myrtle Ave., was booked into East Baton Rouge Parish Prison on a count of malfeasance in office. She has since been terminated from her position with the Office of Juvenile Justice.
