It was a constant flow of mourners who stopped by the Weymouth Police Department Sunday -- so many people paying their respects.
"We knew they were going to be working around the clock and just wanted to show our support and how grateful we are to be a part of this community," said Portia Harrington.
Some people crossed themselves, another brought an American flag. Many arrived with flowers to display as part of the growing memorial, others with food for police, knowing their work never ends.
"It's a tragedy," said Ryan McKinnon. "It affects the whole community, they lay their lives on the line for us everyday, it's the least we can do, bring a few things out for them to help them get through."
Tina Galano met Officer Chesna when she did a ride-along with him when she took part in the Citizens Police Academy.
"He was a great guy and he talked about his children and his wife," said Galano. "It was a great time, he was a great officer."
Officer Chesna was a husband, father of two, and an army veteran. And this was his dream job.
"I was speaking with his mom this morning and she told me that he joined the military to help open the doors for him to get on this job," said Weymouth Police Chief Richard Grimes.
Tomorrow, Officer Chesna would have celebrated his sixth anniversary as part of the police force. A vigil is scheduled for 7 p.m. tomorrow night outside Weymouth High School for both Chesna and the unnamed female victim who was also killed on Sunday.
Chesna worked the midnight to 8 a.m. shift. The incident unfolded as the shift neared its end, around 7:30 a.m.
