CNN) — A profanity-laced video of middle school students in upstate New York verbally abusing a bus monitor is sparking an outpouring of support as strangers worldwide rally to her side.

In the video, the students taunt Karen Klein, 68, with a stream of profanity, insults, jeers and physical ridicule.

Some boys demand to know her address, saying they want to come to her house to perform sexual acts and steal from her.

The bullying continues unabated for about 10 minutes in the video, reducing Klein to tears as a giggling student jabs her arm with a book in one instance.

“Oh my God, you’re so fat,” one says.

Klein, a bus monitor for the Greece Central School District, said she tried her best to disregard the harassment. The students involved attend Greece Athena middle school.

“I tried to ignore it … I didn’t hear some stuff and tried to shut them out,” Klein told CNN affiliate WHAM.

She said one comment from a boy aboard the bus was especially painful. He tells her that she does not have family because “they all killed themselves because they didn’t want to be near you.”

Klein’s oldest son took his own life 10 years ago, according to the affiliate.

CNN attempts to reach all parties involved Wednesday were unsuccessful.
