According to a release from Howard County Police, some of the blood came out of the syringe, but missed the pharmacist.

The suspect, 52-year-old Benjamin Frederick Blessing, fled with over $27,000 in prescription medication on April 18, the release said.

Police said the liquid in the syringe was blood, but they have yet to determine whether it contains the AIDS virus.

Blessing has also been charged in an incident where he allegedly demanded money from a woman at an ATM while holding a Taser gun.

Around 1 p.m. on October 10, the female victim and her 4-year-old child were alone at an ATM in Ellicott City, according to authorities. The victim told police a man approached her with what looked like a Taser gun in his hand. Though he demanded money, none was stolen.

Howard County Police charged Blessing with armed robbery, first and second degree assault, reckless endangerment and theft, the release said.
