OMAHA, Neb. (AP) — The next Omaha Science Cafe will focus on the use of a marijuana plant extract to treat epilepsy.

Cannabidiol is extracted from the Cannabis sativa plant and is different from the extract that provides the high from smoking marijuana.

Dr. Deepak Madhavan is involved in the oversight of a clinical study investigating the use of cannabidiol in patients with drug-resistant epilepsy. At Tuesday’s Science Cafe he’ll discuss the substance and its potential clinical use.

The event is scheduled to begin at 7 p.m. at the Slowdown, 729 N. 14th St.

OMAHA, Neb. (AP) — An Omaha police detective has testified that old files on a former Indiana doctor led to his becoming a suspect in the killings of four people with ties to an Omaha medical school.

Detective Derek Mois testified Friday in the murder trial of Anthony Garcia. Mois said the Creighton University School of Medicine files detailed Garcia’s problems with school faculty like Dr. Roger Brumback, who was killed along with his wife in 2013, as well as with Dr. William Hunter, whose 11-year-old son and housekeeper were stabbed to death in 2008.

Prosecutors say Garcia was motivated by lingering rage over being fired from the school’s residency program in 2001.

Mois said further investigation turned up cellphone and credit card records that put Garcia near Omaha the day the Brumbacks were killed.

WATERLOO, Iowa (AP) — A man acquitted earlier this year in the 2013 death of a teenager has been sentenced to up to five years in prison for fleeing the state after the shooting.

Perquondis Holmes entered an Alford plea in August to a charge of flight to avoid arrest. Police say he fled to Nebraska after the November 2013 shooting death of 18-year-old Dae’Quan Campbell.

Holmes was given credit for nearly three years he spent in jail awaiting trial.

Holmes was previously convicted in the killing, but was granted a second trial because jurors in his first trial saw Facebook photos of Holmes that included gang affiliation, violating an earlier ruling. Holmes was found not guilty in the second trial held in August.

LINCOLN, Neb. (AP) — Two California men have been arrested in Lancaster County after deputies say they found more than 40 pounds of marijuana in their car during a traffic stop.

The men were pulled over Wednesday afternoon on Interstate 80 near the Lincoln airport exit Wednesday afternoon for speeding.

A deputy reported a strong odor of marijuana coming from the car, and a search of it turned up three duffel bags stuffed with marijuana packed in vacuum-sealed bags. Deputies also seized $1,300 in cash.

The two men were arrested.

OMAHA, Neb. (AP) — An ex-exotic dancer says one of her former customers now on trial for the deaths of four people tied to an Omaha medical school told her he had killed “an old woman and a young boy.”

The woman’s testimony came Thursday in the first-degree murder trial of Anthony Garcia. Prosecutors believe Garcia’s words to the stripper were a confession of the 2008 stabbing deaths of 11-year-old Thomas Hunter and his family’s housekeeper, 57-year-old Shirlee Sherman.

The boy was the son of Creighton University School of Medicine faculty member, Dr. William Hunter. Garcia is also charged in the 2013 killings of another Creighton faculty member, Dr. Roger Brumback, and his wife, Mary.

Authorities believe Garcia was motivated by his rage at being fired in 2001 from a Creighton residency program.

OMAHA, Neb. (AP) — Authorities say a man has been treated for smoke inhalation after a house fire in south-central Omaha.

The fire was reported late Wednesday night south of Pipal Park. Fire Battalion Chief Mark Driscoll says there were reports that as many as three people were trapped in the house, but firefighters found only the one man.

The fire cause is being investigated.

MALCOLM, Neb. (AP) — Two Malcolm residents have been accused of severely injuring a 5-year-old girl.

Online court records say 25-year-old Cassondra Karst and 26-year-old Bruce Sampson are charged with intentional child abuse. The records don’t list the names of attorneys who could comment for Karst or Sampson. Both have hearings scheduled for Oct. 31.

The records say Karst called deputies to the Malcolm residence on June 16, saying the girl had fallen down some stairs. Medical officials later told investigators the girl had several old injuries and that bleeding in her brain could have been caused by being shaken or by blunt force.

State authorities have taken the girl into emergency protective custody.

SIOUX FALLS, S.D. (AP) — A Sioux Falls man is accused of sitting on a woman and slicing off her nipples with a pair of scissors.

Police spokesman Sam Clemens says 45-year-old Tony Ledbetter attacked the woman during an argument Tuesday. He’s charged with domestic aggravated assault.

The 39-year-old woman was hospitalized but no information about her condition has been released.

Clemens says the woman told investigators Ledbetter also punched her, slammed her head on the ground and tried to stop her screaming by putting his forearm on her throat and stuffing a blanket in her mouth.

A judge entered a not guilty plea on Ledbetter’s behalf Thursday and set bond at $250,000 cash. Defense attorney David Stuart says Ledbetter is unlikely to post bond.

COUNCIL BLUFFS, Iowa (AP) — Authorities have accused a Council Bluffs man of stealing some of his grandmother’s jewelry and pawning it.

23-year-old Colton Rankin was arrested Wednesday and is charged with theft and burglary. Court records don’t list the name of an attorney who could comment for him.

Council Bluffs police say the woman noticed Sept. 12 that someone had gotten into her jewelry boxes and taken some items. Court records say she told police she suspected her grandson because of what she said was his drug problem. Her family checked with his employer in the Omaha, Nebraska, suburb of La Vista and learned that Rankin had not gone to work that day.

Police say Rankin later told a relative that he’d pawned the jewelry in Omaha.

STORM LAKE, Iowa (AP) — The small northwest Iowa city of Storm Lake has a low unemployment rate, vibrant downtown and tree-lined neighborhoods, but it’s also facing a surge in hunger that’s familiar to rural communities across the country.

The community is struggling to respond as thousands of working families and elderly residents seek help feeding themselves or their children. The issue persists even as national poverty rates have declined and food prices are down.

In Storm Lake, residents are helping their neighbors with a large, mostly volunteer effort to hand out free food at a half-dozen pantries, along a city street and in an empty building.

Hermelinda Gonzalez relies on a monthly drive-up pantry to feed her seven children despite her husband’s construction job. She says, “I don’t know what we’d do without this.”
