A man accused of wounding two drivers when he fired at least 70 rounds from an assault-style weapon on a busy street near Boston pleaded not guilty Thursday to assault and other charges.
Tyler Brown, 46, who appeared in Cambridge District Court via video from a hospital bed, did not speak and appeared to have his eyes closed for most of the brief hearing. He nodded when the judge said not guilty pleas had been entered on his behalf to charges of armed assault with intent to murder and six other charges, including possessing a gun without a license.
