Boston- A former strip club waitress was sentenced Wednesday to five years of supervised release after she pleaded guilty to mailing threatening letters and flammable material, including condoms filled with a potentially explosive mixture, court documents said.

The documents said Kimberly Lynn Dasilva, 49, of Hull, mailed the condoms to a television station, strip clubs where she had worked and other places, saying she was tired of being mistreated by men. In May, she pleaded guilty to mailing threatening communications and a violation of injurious articles as nonmailable.

U.S. District Judge George O’Toole sentenced Dasilva to the supervised release with conditions, including not contacting victims, receiving mental health counseling and treatment, performing 500 hours of community service and refraining from alcohol.

None of the condoms exploded. Dasilva told investigators she did not think they would explode.
