After parents recently learned that a Montgomery County music teacher was charged with sexually abusing 14 girls in kindergarten to second grade at a Silver Spring elementary school, some have asked about the educator’s previous work history.

Montgomery County school officials say Lawrence W. Joynes, 54, who is held in jail on $1 million bond, worked in 11 county schools during his 27-year career, mostly in Silver Spring.

Beginning in August 1985, Joynes worked at the following county schools:

*From August 1985 to August 1990, Joynes was mainly assigned to Cannon Road Elementary School in Silver Spring, with 20 to 30 percent of his work week divided between other schools: Olney Elementary School in Olney; Highland View Elementary School in Silver Spring; Rolling Terrace Elementary School in Takoma Park; and Stonegate Elementary School in Silver Spring.

*From August 1990 to August 1997, he worked at Eastern Middle School in Silver Spring.

*From August 1997 to July 2002, Joynes was mainly at Francis Scott Key Middle School, but he spent 10 percent of his work week at Kemp Mill Elementary School and another 10 percent at Cresthaven Elementary School. All three schools are located in Silver Spring.

*From July 2002 to July 2003, he was at both Sligo Creek Elementary School in Silver Spring and New Hampshire Estates Elementary School, splitting his time between the two schools.

*His longest stay was at New Hampshire Estates, where he worked from 2003 until his arrest earlier this year.

Police say that families with concerns about their children should call the family crimes division of the Montgomery County police department at 240-773-5400.

“We are always interested in hearing from any parent, even if they are just suspicious,” said Montgomery Police Capt. Bob Carter.

The sexual abuse charges filed against Joynes in August involve offenses over a period of eight school years at New Hampshire Estates. Much of the alleged abuse took place on school grounds, during the school day, according to court documents.

Joynes is also charged with second-degree rape and other offenses in connection with his alleged abuse of a female student at Eastern Middle School from 1991 to 1993.

He was first arrested in late February on a charge of child pornography in Baltimore County, after a federal investigation led to his home in Dundalk.
