LAWRENCE — A 19-year-old Topeka native who had been missing for nearly two weeks has been charged in the death of a Lawrence man, authorities announced Monday.

Lawrence police Chief Tarik Khatib identified Sarah Brooke Gonzales McLinn as a suspect in the slaying of Harold Sasko, 52, at a news conference Monday afternoon at the Law Enforcement Training Center. Park rangers located McLinn late Saturday camping in a car registered to Sasko in the Everglades National Park, Khatib said.

Police aren't looking for other suspects in the slaying.

"We believe she was the only one involved," Khatib said.

Khatib said the park service rangers found McLinn camping illegally in Everglades National Park and in possession of a suspected controlled substance. She now is in federal custody in Homestead, Fla., according to Douglas County District Attorney Charles Branson.

Branson said McLinn has been charged with intentional and premeditated first-degree murder in Douglas County District Court.

The District Attorney's Office requested and received a warrant for McLinn’s arrest Sunday, Branson said. He said McLinn was undergoing a first appearance in Florida in connection with federal charges incurred in the Everglades National Park, but those charges will be dropped in favor of extradition on the murder charge.

Police discovered Sasko’s body Jan. 17 when they went to his residence in the 2900 block of W. 26th, near the southwest corner of Holcom Park, to check on McLinn, who lived there with Sasko and hadn’t been heard from since Jan. 14.

Khatib said the coroner’s office hasn’t yet released a time or date of death for Sasko, who he said was killed by "an edged instrument." The charge filed against McLinn alleges Sasko was killed on or about Jan. 14.

"We believe Mr. Sasko was somehow subdued," Khatib said, adding later, "We don't believe he was conscious."

He said police believe they have found the murder weapon.

Khatib said the charge against McLinn was a result of officers not being satisfied with just knocking on Sasko’s door Jan. 17. Since then, he said, officers have been "working around the clock" to investigate his death.

McLinn wasn’t identified as a suspect in Sasko’s death until Monday’s news conference, Khatib said, because law enforcement wasn’t sure on that point.

"We didn’t know," he said.

Sasko owned two Cici's Pizza restaurants in Topeka and one in Lawrence. They have remained open since his death.

Khatib said the relationship between Sasko and McLinn remained unclear.

Lawrence police said McLinn was found after a nationwide search bulletin was issued for her and Sasko’s 2008 Nissan Altima through the National Crime Information Center. Investigators pursued leads through multiple states before being contacted by the Everglades National Park Service rangers.

Lawrence police detectives flew to Miami on Sunday morning to interview McLinn and process additional evidence.

If McLinn waives extradition, Branson said, she could be returned to Kansas this week.

Sasko’s dog, Oliver, also was missing from his residence along with the car in which McLinn was found, Khatib said. He said officials believe the dog is at a Florida veterinary clinic.

McLinn attended Shawnee Heights High School before graduating in 2012 from Topeka High.
