DENVER (AP) — Denver is starting work on becoming the first city in the nation to allow marijuana clubs and public pot use in places such as coffee shops, yoga studios and art galleries.

Voters narrowly approved the “social use” measure last November. But the ballot proposal didn’t spell out many rules for how the marijuana could be consumed, beyond saying that the drug can’t be smoked inside and that patrons must be over 21.

A workgroup made up of Denver business owners, city pot regulators and marijuana opponents starts work Wednesday on suggesting regulations.

The state Liquor Control Board already has decreed that no businesses with a liquor license can allow marijuana use. That leaves it to restaurants that don’t serve alcohol and other event spaces.

There’s no deadline for Denver to finalize rules.

OMAHA, Neb. (AP) — A 54-year-old man has been sentenced to life in prison — plus 126 years — for a 2015 shooting that left two people dead and another injured.

Michael Nolt was sentenced Thursday in Douglas County District Court. He was found guilty last October of first-degree murder and manslaughter for the Oct. 10, 2015, deaths of Malquan King and Arelius Hassell.

Prosecutors say the shootings were part of a botched robbery. They say Nolt shot Hassell in the face after a brief argument, and then shot two other people hiding in a closet, killing King.

Six children in the house at the time were not hurt.

EDGEMONT, S.D. (AP) — Two BNSF Railway employees have been struck and killed by a train near Edgemont in southwestern South Dakota.

A company statement says the accident happened around 10:15 a.m. Tuesday.

The scene is just north of where the tracks cross under U.S. Highway 18 near Edgemont. BNSF operates a rail yard on the east side of Edgemont.

The railroad’s statement says company officers are responding to the incident and will release more details when they are able.

Edgemont is about 60 miles southwest of Rapid City.

FREMONT, Neb. (AP) — An Arlington woman has been given 90 days in jail for the death of a memory care patient who was burned after falling asleep near a fireplace.

Court records say Anne Pavlik was sentenced Tuesday in Dodge County Court. The judge also gave Pavlik two years’ probation. She’d pleaded no contest to attempted abuse of a vulnerable adult in the death of 82-year-old Bernard Batten at a Fremont memory care center.

Investigators determined Batten awoke early on Feb. 12 and eventually sat in a chair. Pavlik, who was the only staffer on duty, didn’t notice Batten then pulled his chair near a fireplace fire and fell asleep.

Pavlik later found Batten was badly burned. An autopsy showed he died of natural causes and burns.
