JEFFERSON CITY, Mo. (AP) — Missouri senators have returned to the Capitol to debate abortion legislation but haven’t yet taken action.

Senators met Monday to work on a wide-ranging abortion bill that would impose new regulations on the procedure, among a number of other provisions.

Senators didn’t take a vote on whether to adopt stricter proposals recommended by the House or to stick with a watered-down version that already received Senate approval. Differences in the House version include a provision that would make it a crime for abortion clinic staff to ask ambulances to respond to calls without lights or sirens.

House members passed the measure more than a month ago. Senate leaders say work has been delayed because of scheduling issues.

Senators are going back to work on the bill Tuesday.

ST. LOUIS (AP) — A man is charged with attacking four homeless people with a hammer as they slept in a vacant St. Louis school building, critically injuring two of the victims.

Sixty-one-year-old Edward Moore was charged Sunday with four counts of assault and armed criminal action. Bond is set at $500,000. No attorney is listed for him in online court records.

Police said in a news release that the four victims were taken to a hospital Saturday after they were found suffering from “head trauma.” The release says a man and woman were listed in critical condition, with the woman unstable. Another man and woman were listed as stable.

The former school north of downtown closed in 1978.

Homicide detectives have been called to handle the investigation.

TOPEKA, Kan. (AP) — An eastern Kansas woman accidentally has set her apartment on fire in an attempt to kill a bug by burning it with a small, flip-style lighter.

Monique Quarles tells The Topeka Capital-Journal that sparks shot out of the lighter and caused a mattress to catch fire in the Fairlawn Green Apartments complex in Topeka.

After she was unable to put out the fire, Quarles left the unit with two others and began alerting residents of the fire. Fire officials say 13 adults and six children have been displaced.

Topeka Fire Department Battalion Chief Chris Herrera says one person was taken to the hospital for minor smoke inhalation.

Officials estimate that the fire caused $140,000 in damage.

The apartment complex was the scene of another large fire in July 2016.

JEFFERSON CITY, Mo. (AP) — Some Democratic Missouri lawmakers are reviving efforts to prevent cuts to in-home and nursing care for the elderly and disabled.

The Republican-led Legislature passed a bill this year to restore funding for about 8,300 seniors and disabled people at risk of losing in-home and nursing care through a Medicaid program. But Republican Gov. Eric Greitens vetoed that bill.

In response, three House Democrats on Monday asked the state not to request a federal waiver to cut services. Democratic Springfield Rep. Crystal Quade and others also said lawmakers should try to override Greitens’ veto.

Lawmakers have a chance at overriding the governor in September, but it’s unclear whether there will be enough support if there’s a vote. The measure passed the House in May without enough votes for an override.

SIOUX CITY, Iowa (AP) — Iowa state law requires all evidence that’s been filed in court and used in cases be kept by court clerks well after convictions in case of appeals or if new technology emerges that could test evidence in a new way.

EMPORIA, Kan. (AP) — Emporia residents no longer have to boil their water.

JEFFERSON CITY, Mo. (AP) — A man died and two females were critically injured in an apparently accidental carbon monoxide poisoning at a Jefferson City home.

Jefferson City police say emergency responders were called to the home early Saturday for a medical emergency.

Responders found 51-year-old Troy Feltrop dead in the home. Two females, 44-year-old Lisa Feltrop and a 14-year-old girl, were taken to hospitals. Police say they are both in critical condition.

Police detectives determined a vehicle was left running in the garage overnight, filling the house with carbon monoxide.

Police say the early investigation indicates the incident was an accident.

No further information was immediately released.

OLATHE, Kan. (AP) — One of four men charged in the shooting death of a Kansas gun store owner will have to serve at least 33 years in prison before being eligible for parole.

Londro Patterson III was sentenced to life in prison Friday for the January 2015 fatal shooting of Jon Bieker at the She’s a Pistol gun store in Shawnee.

Bieker and his wife, Becky Bieker, owned the store. He was shot when he exchanged gunfire with suspects during an attempted robbery.

The Kansas City Star reports prosecutors say another man fired the shot that killed Bieker but the four men were all charged with murder because they allegedly participated in a robbery that led to the killing.

Another defendant is awaiting sentencing, while the other two are awaiting trial.

KANSAS CITY, Mo. (AP) — Mediation is the next step for a federal lawsuit that alleges a former Missouri police officer nearly killed a teenager with a stun gun during a 2014 traffic stop.

Bryce Masters’ lawsuit was filed against the city of Independence, its former police chief and the former officer who fired the stun gun, Timothy Runnels. Online court records show a mediator will hear the case Aug. 9.

Witnesses testified that Masters went into cardiac arrest when Runnels shot him with a stun gun after Masters refused to get out of his car. Masters was 17 at the time.

Video from Runnel’s patrol car shows Runnels using the stun gun and, after Masters goes limp, handcuffing and dragging him to the curb. Runnels is serving a four-year prison sentence for violating Masters’ civil rights.

CHICAGO (AP) — Cancer patients’ gray hair unexpectedly turned youthfully dark while taking novel drugs, and it has doctors scratching their heads.

Chemotherapy is notorious for making hair fall out, but the 14 lung cancer patients involved were all being treated with new immunotherapy drugs that work differently and have different side effects. A Spanish study suggests that may include restoring hair pigment.

All but one patient had at least stable disease and responded better to treatment than other patients. That suggests that hair darkening might be an indication that the drugs are working. But the researchers say more study is needed to show their results aren’t a fluke, and to answer how the drugs might change hair color.

The study was published online this month in JAMA Dermatology.
