Ohio police said on Tuesday that a 45-year-old man arrested that morning is a suspect in both the triple homicide of a mother and her two adult daughters, who were found dead on Sunday, and the fatal shooting of a couple found dead on Monday.
Here are five things to know about the case.
1. Suspect Arrested After Allegedly Barricading Himself
George Brinkman was taken into custody about 5:30 a.m. Tuesday after an hours-long standoff, according to authorities.
He had allegedly barricaded himself inside a home in Brunswick, Ohio, police Lt. Steven Hoover told PEOPLE. Hoover said Brinkman was armed with a gun and that a woman in the home with him when the standoff began later left the residence unharmed.
Authorities used a Taser to take Brinkman into custody, Brunswick police Lt. Robert Safran told local TV station WJW.
Footage of the incident showed a shirtless man wearing red shorts being led from the home by police in handcuffs.
2. Three of Suspect’s Alleged Victims Found in the Same Bed
Police in North Royalton, Ohio (about 15 minutes from where Brinkman was arrested), told PEOPLE the body of 45-year-old Suzanne Taylor was found Sunday night in her bed beside the bodies of her daughters, 21-year-old Taylor Pifer and Kylie Pifer, 18.
The three bodies were found under the covers, almost as though they’d been tucked into bed, according to North Royalton police detective Dave Loeding.
Forensic evidence collected from the scene is being investigated, he said. Autopsies are also being conducted.
“[We] feel confident that all the things we’re doing are going to turn into a positive outcome,” he said.
3. It Wasn’t Immediately Clear How Taylor’s Daughters Died
Loeding told PEOPLE that Taylor appeared to have died after sustaining a knife wound, but her daughters didn’t seem to have “obvious signs of death” — though police believe both daughters were homicide victims.
Investigators think the killings were targeted, not random, according to Loeding.

Police received a 911 call from Taylor’s boyfriend on Sunday night, Loeding said, claiming that one of the girl’s boyfriends called him after finding their bodies.
Upon arrival, investigators noticed there appeared to be no signs of forced entry, Loeding said. Police suspect the daughters were killed elsewhere in the home before their bodies were moved to their mother’s bed.
4. Suspect Accused of a Double Homicide in Nearby County
Police announced at a Tuesday news conference that an arrest warrant was taken out for Brinkman on two murder charges in the deaths of Rogell John, 71 and his 64-year-old wife, Roberta.
Authorities arrived at the couple’s home in Lake Township, Ohio (about an hour from North Royalton) on Monday, after Rogell’s son called police when he found his father and stepmother unresponsive.
“I just stopped by my dad’s house to check on him and I think he and his wife might be dead,” the man’s son said in a frantic 911 call. “He’s on the bed, she’s on the floor.”
Stark County, Ohio, Sheriff George Maier said at the news conference that Brinkman dated the Johns’ daughter in the past, but the two had a strained relationship. Brinkman also worked at the family’s business for a number of years, Maier said.
He added that police are working to determine a possible motive for the shooting.
Brinkman is being held by North Royalton authorities. It is not clear if he has yet been charged in the three other deaths, in North Royalton, or if he has retained a lawyer or entered a plea.
5. Family of Mom and Daughters Has Spoken Out
Kylie and Taylor’s stepmother told WJW that the family was blindsided by their deaths.
“They were great kids. Taylor and Kylie were great students,” she said.
“Taylor was majoring in fashion design, while Kylie was involved in theater and was majoring in forensic science.”
