HAVERHILL — Police said they are charging a Haverhill man with mailing a thank-you card containing a powdery substance to a local law office, one of four Merrimack Valley businesses that received similar envelopes.
Police Deputy Chief Donald Thompson said complaints have been filed against the man and he will be summonsed to court to face a charge of possession a hoax substance. Thompson would not say when the man will appear in court or discuss where he is currently. Thompson said police do not release the names of suspects until they have either been arrested or appear in court on a summons.
Earlier in the investigation, police said the man is “mentally ill’’ and that the substance turned out to be baking soda in all four cases.
Lawrence police Chief John Romero said he will confer with Haverhill police to determine whether his department will go forward with any charges since the incident involved his community as well. Police have said they believe the same person mailed all the envelopes involved.
The scare happened Nov. 19, when three nearly simultaneous reports of suspicious white powder were reported, prompting a massive response by local and state police, the FBI, the state Department of Fire Services, and the Regional Hazardous Materials Response Team to the Home Depot in Methuen, Home Health VNA in Lawrence, and the Edwards Law Office next to the police station in Haverhill.
Later in the day, another card was received at a North Andover business at 85 Flagship Drive, which also resulted in a response by a HazMat team and investigators.
Later that day, Haverhill police said they had a suspect, but no arrest had been made. Detectives searched an apartment at 46-48 S. Main St. about noon, leaving the scene with several plastic bags containing what appeared to be stationary and other items.
