The Ute Mountain Casino in Towaoc reopened on its normal schedule Friday morning after an emergency closing because of the manhunt in Bluff, Utah.

Fearing the fugitives may be heading toward Towaoc, managers closed the casino Thursday night at 6 p.m.

"The information we were receiving indicated the men may be heading in our direction," said René Howe, general manager of the casino. "We decided the safety of our visitors was much more important than remaining open."

The shooting of a fourth police officer outside of Bluff Thursday afternoon prompted a series of highway road blocks and an infusion of law enforcement into the small town in southeastern Utah 40 miles west of Towaoc.

As the search moved outside of Bluff, managers decided to reopen the casino.

"The intensity of the search today doesn’t seem as strong as it was last night," Howe said.

Despite the search, Howe said business at the casino has remained strong.

MONTICELLO, Utah (AP) — The Bureau of Land Management Friday indefinitely closed the San Juan River and hundreds of thousands of areas of surrounding scenic canyon country as lawmen expanded their search for a pair of suspected cop-killers.

Kent Walter, manager of the BLM’s San Juan Management Area, said any rafters and boaters on the 22-miles of river between Bluff and Mexican Hat will be pulled from the river.

Montezuma County Sheriff Sherman Kennell said a roadblock in southwestern Colorado to find three fugitives has yet to turn up a cop-killer, but it has uncovered almost a half-ton of marijuana.

A checkpoint at the intersection of U.S. Highway 160 and state Highway 41 near the Four Corners Monument was set up Thursday after suspects accused of shooting three police officers near Cortez allegedly shot a fourth near Bluff, Utah.

"And in less than 24 hours, we found three large loads of dope," Kennell said.

Kennell said authorities who pulled over a Chevy Camaro Thursday night found 150 pounds of marijuana hidden in the car.

Friday morning, a search of a Chevy Suburban turned up 500 pounds of marijuana. And a walk-through of a motor home uncovered 250 pounds of the drug later that afternoon.
