“We love and miss her,” the message read. “Her gentle spirit of kindness and warmth will be with us in the restaurant every day. We raise a glass to her.”
Rich Barron, the restaurant’s owner, remembered O’Connor as “the sweetest, most wonderful person ever.”
“We’re going to celebrate her every day,” he said.
Jeannine O’Connor was raised in Watertown, where she was a graduate of St. Patrick’s High School. She leaves her children, Jessica A. Crusco and her husband, Stephen, of Waltham, Colleen M. O’Connor and her fiancé, Brendon Clark, of Boston, and Ryan C. O’Connor of Waltham; her sister, Cheryl Martino and her husband, Tony, of Watertown, and several nieces and nephews.
About one-third of domestic violence homicides nationally are followed by a suicide, said Toni Troop, a spokeswoman for Jane Doe Inc., the Massachusetts Coalition Against Sexual Assault and Domestic Violence.
In Massachusetts, about 24 percent of fatal domestic violence incidents from 2003 to 2012 included perpetrators who committed suicide. Over that span, domestic violence accounted for 14 percent of all homicide deaths in the state, the group said in a report released last year.
Nearly 90 percent of domestic homicides are committed by men, and almost 72 percent of victims are female, the report found.
“It is the very rare circumstance where there was no history of domestic violence and abuse,” Troop said. “In the vast majority, there are clear warning signs for lethality.”
Kevin O’Connor, a lifelong resident of Waltham, was a retired detective and had worked as a private investigator, according to his obituary. In 2002, O’Connor was placed on paid leave after he was arrested and charged with drunken driving. He pleaded not guilty.
Most recently, he had worked at Fiorella’s Restaurant in Newton, where he was scheduled to work as a bartender Saturday night but did not show up. Employees called to check on him, but he never picked up.
Police found the couple after a family member called asking for a well-being check. Police remained at the home throughout the night, and removed at least two rifles and a small box.
