Police say that a suspect in the shooting death of a Michigan parent was arrested in Detroit.

The parents of a Michigan teenager who the police say fatally shot four classmates in the halls of Oxford High School in suburban Detroit were arrested early Saturday after being the subject of an intense manhunt.

The teenager’s parents, James and Jennifer Crumbley, were taken into custody in a commercial building in Detroit after the police received a tip that led them to the location, officials said. Arriving officers spotted their vehicle and moved in to arrest them. It came a day after they were charged with involuntary manslaughter in the deaths, failed to show up for their arraignment and apparently fled town.

“We have in fact taken them into custody without incident,” James E. White, Detroit’s police chief, said at an early-morning news conference. “They appeared to be hiding in the building,” he said, adding, “We got a tip that they were there.”

“They did not resist” when officers moved in to arrest them, he said, describing the couple as “distressed.”

The couple were charged in the students’ deaths after officials said their son, Ethan Crumbley, 15, carried out the shootings on Tuesday using a handgun his parents had bought for him.

On Friday, Karen D. McDonald, the Oakland County prosecutor, said the Crumbleys were culpable in the year’s deadliest school shooting because they had allowed their son access to a handgun while ignoring glaring warnings that he was on the brink of violence.

Law enforcement officials said that the parents had gone missing on Friday afternoon, prompting a manhunt that involved the county’s fugitive-apprehension team, F.B.I. agents and United States Marshals. It drew in the Detroit police when officials received the tip that led them to the area where Saturday’s arrest took place, just north of the Detroit River.

“They cannot run from their part in this tragedy,” Sheriff Michael Bouchard of Oakland County said in a statement on Friday, before the couple were apprehended.

The deadly gunfire in Oxford, in Oakland County — about 30 miles north of Detroit — added to a growing list of shootings this year on school grounds in the United States after a lull during the early months of the coronavirus pandemic, when many schools held classes remotely.

In announcing the charges against the parents, Ms. McDonald gave a detailed accounting of Ethan Crumbley’s alleged actions leading up to the shooting.

On the morning of Nov. 30, the day of the shooting, she said, the suspect’s parents were urgently called into the high school after one of his teachers found an alarming note he had drawn, scrawled with images of a gun, a person who had been shot and a laughing emoji, and the words, “Blood everywhere,” and, “The thoughts won’t stop. Help me.”

The day before the shooting, a teacher had seen the suspect searching online for ammunition for the gun in class, which led to a meeting with school officials, the prosecutor said. After being informed by the school about their son’s behavior, Ms. McDonald said, Mrs. Crumbley texted to her son: “LOL, I’m not mad at you. You have to learn not to get caught.”

The shooting took the lives of Hana St. Juliana, 14; Madisyn Baldwin, 17; and Tate Myre, 16, who died in a sheriff’s squad car while on the way to a hospital. A fourth student, Justin Shilling, 17, died on Wednesday morning at McLaren Oakland Hospital in Pontiac, Mich.
