Later in the day, another card was received at a North Andover business at 85 Flagship Drive, again bringing out the HazMat team and investigators.
Haverhill Police on Monday said they had a suspect, but no arrest had been made. Detectives searched an apartment at 46-48 S. Main St. in Haverhill about noon on Monday, leaving with several plastic bags containing what appeared to be stationary and other items.
Joseph Edwards, owner of Edwards Law Office at 60 Bailey Boulevard in Haverhill, was one of those who received a card. After hours of waiting for a HazMat team to deem his office safe on Monday, Edwards was relieved yesterday to have a more normal day.
Yesterday turned out to be a normal day, Edwards said, although he had one burning question for the letter carrier who arrived at his office with his mail.
“I asked him if the mail was safe, and he laughed,” Edwards said.
Edwards said the big question on everyone’s mind yesterday was what he might have in common with the other businesses that received envelopes containing thank-you cards and a white powdery substance. He said people he bumped into and who called him on the phone asked if he was alright, and why he was sent one of the envelopes.
“I told them I didn’t have the slightest idea,” Edwards said.
