IN BRIEF:

HOMELESS KILLED-DENVER— A parolee suspected of killing three homeless people has been charged with three counts of first-degree murder. The Denver District Attorney's Office says 38-year-old Maurice Butler was charged late Monday.

WILDFIRE LAWSUIT — More than a half dozen Colorado residents and businesses have filed a lawsuit against a train, accusing it of starting a wildfire that scorched about 85 square miles (220 square kilometers) of mostly federal land. The Durango Herald reports the lawsuit, filed Friday against the Durango & Silverton Narrow Gauge Railroad, says the wildfire, sparked June 1 near Durango, was started by burning material emitted from a coal engine that travels from Durango to Silverton.

LAFAYETTE-FATAL FIRE-ID — Officials have released the name of a 73-year-old woman who died in a Colorado house fire last week. The Boulder County coroner's office tells the Daily Camera that Linda Radcliffe was found dead after a Sept. 5 fire at her residence in Lafayette, east of Boulder.

HOMICIDE-NEGLECTFUL CARE — The Denver medical examiner declared an 88-year-old woman's death a homicide because of inadequate medical care. The Denver Post reports the examiner says Mary Smith died May 22 at an area hospital after her primary caretaker did not follow her care plan, seek medical attention or provide adequate nutrition or medications as required.

THOMPSON DIVIDE DRILLING — A lawsuit challenging the cancellation of oil and gas leases in the Thompson Divide area in western Colorado is over. U.S. District Judge Robert E. Blackburn dismissed the case last week following a settlement reached earlier this summer between the Bureau of Land Management and energy company SG Interests. The BLM agreed to pay the company $1.5 million for 18 oil and gas leases it cancelled in 2016 at the request of a coalition of governments, environmentalists, ranchers and others.
