ISHPEMING, Mich. (AP) — State police still are searching for two sisters from Nebraska and Oklahoma who have been missing for a week during a trip in Michigan.

Det. Sgt. Jeff Marker said Saturday there have been many tips but still no sign of 52-year-old Leslie Roy and 56-year-old Lee Marie Wright. He says they checked out of a motel, ate breakfast and got gas in Ishpeming in the Upper Peninsula on April 11.

But they didn’t appear as planned that night in Mackinaw City, three hours away. Marker says Roy and Wright had visited relatives in Ishpeming.

Marker says Roy is from Valley, Nebraska, and Wright lives in Depew, Oklahoma.

They’re traveling in a white Ford Explorer with a Nebraska license plate. Anyone with information can call police at (906) 475-9922.
