To my surprise no one of the Facebook group "Way With Words" could come
up with a plausible answer.
A woman mentioned that when she was a kid, her gym teacher got arrested.
When the kids asked "why?" they were told he was "stringing beans" and
they'd find out when they were older.
To me it was pretty obvious it was a sex crime but I cannot find that
term in any on-line slang dictionary.
After a visit to Green's Slang Dictionary, I'm none the wiser. It doesn't
seem to be a conventional expression, except in the literal sense having to do
with removing unwanted parts from vegetables.
"Bean" has a whole lot of possible meanings. Could it have had some reference
to Mexican-Americans? If not, then try the old favourites, sex (2(a) 'the penis', (b) 'the hymen', (c) 'the clitoris') and drugs (4 (a) 'a package of a drug'; (b)'any form of tablet').
"String" can mean "to work as a pimp, i.e. to run a string of prostitutes",
or like "string along": "to fool, to deceive someone, esp. over a drawn-out period of time; to tease".
Still doesn't add up to anything obviously right. Look forward to further
