Yarmouth police officer Sean Gannon wasn't the only victim of Thursday afternoon's shooting in Barnstable.
Tom Latanowich, 29, has had more than 110 prior criminal charges.
Thomas Latanowich made a brief appearance in Barnstable District Court on Friday.
A man described by authorities as a career criminal is heading to court to face a murder charge in the shooting death of a MA police officer.
The Yarmouth Police Department is holding a vigil Saturday night to honor a police officer killed on duty. Nero was also shot in the face and neck during the attack. He was married with no children.
"The men and women of the Yarmouth Police Department are proud to report that our beloved K-9 Nero is back on his feet - Fighting back and standing strong", the department wrote.
Over the weekend Yarmouth police posted a picture of Nero walking.
Police Chief Frank Frederickson said Gannon's death is hard for members of his department to comprehend.
Latanowich is expected back in court in June.
