A 50-year-old Gaithersburg woman, who allegedly tried to hire a representative of a computer dating service to kill her former husband, was indicted Thursday by a Montgomery County grand jury on charges of solicitation to commit murder and assault with intent to maim.

Last March 18, according to police records filed in Montgomery County District Court, Vincent Michael McCarthy went to Ruth Betty Blosser's apartment at 19307 Club House Dr. to interview her about membership in Compatibility Unlimited, a computer dating service. Blosser allegedly told McCarthy about her recent divorce from Harold Blosser, administrator of the Veteran's Administration Hospital psychiatric ward in Chillicothe, Ohio, according to the records.

Blosser allegedly offered McCarthy $5,000, then $10,000, to kill her former husband, and proposed a plan that she said would deflect suspicion from herself and McCarthy, the police reports said.

She allegedly told McCarthy that patients under psychiatric care at the hospital routinely threatened to kill her former husband and, if he died, a patient likely would be accused, police records state. McCarthy agreed to consider Blosser's proposal and keep in touch with her, according to the records.

McCarthy, who reported Blosser's proposal to police, kept in touch with her and she allegedly repeated the offer during a telephone conversation on July 11, offering him a ring valued at $3,800 and a promise to pay the $5,000 balance in installments if McCarthy would agree to kill her former husband, according to police reports.

Montgomery County police Detective Robert F. Renee checked with the Ross County, Ohio, sheriff's department and was told by Sheriff Thomas Hamman that he had handled numerous domestic problems at the Blossers' Ohio home, according to police records.
