In a somber ritual, about 3,000 police officers paid their last respects to slain Weymouth police Sergeant Michael C. Chesna at a Hanover church Thursday afternoon, police said.
The walk-by at St. Mary of the Sacred Heart church was to be followed by a wake for family and friends from 4 p.m. to 8 p.m. Chesna’s funeral is at 11 a.m. Friday at the church.
Chesna was shot and killed Sunday morning in Weymouth, allegedly by 20-year-old Emanuel A. Lopes. Lopes also allegedly killed a bystander, 77-year-old Vera Adams.
As law enforcement officers gathered at the Hanover church Thursday, Governor Charlie Baker said he would support renaming the Fore River Bridge after Chesna.
Speaking to a Boston radio host, Baker said, “I think that is a great idea.”
“If the local legislators were interested in doing that, that’s the kind of stuff that moves pretty quickly,” Baker said in an interview with Greg Hill on WAAF-FM.
Baker said he planned to attend the wake with Lieutenant Governor Karyn Polito.
State Senator Patrick M. O’Connor, whose district includes Weymouth, said he would support renaming the bridge for Chesna, but wants to speak with the officer’s family before proceeding with legislation.
“With that said, this would be a fitting honor for a true son of Massachusetts and hero that was taken from us far too soon,” he said in an e-mail.
The Fore River Bridge, which underwent a yearslong $272 million replacement project, reopened to vehicle traffic last year. It carries Route 3A from Weymouth into Quincy.
Chesna, who was posthumously promoted to sergeant in the Weymouth department, left behind a wife and two young children. He was a decorated US Army veteran who had served two tours with the 10th Mountain Division.
Lopes is also accused of firing three shots into the Torrey Street home of Adams, fatally wounding her. Funeral arrangements for Adams were being prepared by relatives and close friends of the retired insurance company employee.
Lopes was arraigned Tuesday in Quincy District Court, where not-guilty pleas to six charges, including two counts of murder, were entered on his behalf. Lopes was ordered held without bail after a court clinician concluded he was mentally competent.
For South Shore residents, the wake and funeral for Chesna are likely to cause significant traffic delays because of closures of roads around the church.
The town announced the following closures:
■ On Thursday beginning at noon, Hanover Street (Route 139) will be closed, and detours will be in place between Silver and Rockland streets. “Access to any streets in this area will be limited to emergency response vehicles only,’’ according to a town posting. The detour will be in effect until 5:30 p.m.
■ On Friday, the roads around St. Mary’s will close at 9 a.m., and detours will be in place until 2 p.m.
Lopes had repeated encounters with police before he allegedly shot Chesna and Adams, prosecutors have said.
Baker also discussed toughening rules to limit when repeat offenders can be released from custody, similar to rules passed a few years ago in domestic violence cases.
Those changes in handling cases of suspects involved in allegations of domestic violence followed the 2013 killing of Jennifer Martel by her boyfriend, Jared Remy, in Waltham.
“We’ve been having conversations with people in law enforcement and criminal justice primarily about dangerousness and bail, and those are the two areas where we have our best opportunity to pursue reforms on this,” Baker said.Danny McDonald of Globe staff contributed to this report.
