FORT LAUDERDALE, Fla. (AP) — A study by federal health investigators warns that some foster children are not getting their required medical screenings even though the visits are paid for by Medicaid.

The Health and Human Services’ inspector general study released Monday looked at a random sample of roughly 400 foster children from California, Texas, New York and Illinois. It found nearly 30 percent did not receive one or more of their required health screenings between 2011 and 2012. Of those who did not receive at least one required screening, 12 percent didn’t get an initial screening and 17 percent didn’t receive one or more periodic screenings.

Experts say foster children experience high rates of chronic medical, developmental, and mental health issues. They often face challenges getting access to health care.

GRAFTON, N.D. (AP) — A woman is accused of locking four young children in a dog cage in a North Dakota basement and turning out the lights as punishment.

23-year-old Jordan McKay Nelson is charged with four counts of abuse and neglect of a child, and felonious restraint.

Court documents say the children, aged from 5 to 9 years, were held under “terrorizing conditions” and that at least one of them was forced to eat dog food.

During a police interview, a boy drew a picture of himself in the kennel with the words “help me.”

A police affidavit says Nelson is in a relationship with the children’s biological mother. Her lawyer did not immediately return a phone call seeking comment.

A preliminary hearing is set for April 13.

WASHINGTON (AP) — President Barack Obama says now is the moment for police to make changes that build trust in minority communities.

The president on Monday announced findings of a policing task force he appointed in response to the fatal shooting of an unarmed black 18-year-old by a white police officer in Ferguson, Missouri.

Obama says the shooting in Ferguson and another in New York City exposed “deep rooted frustration” in communities of color. Obama says the task force found that police must improve trust with their communities.

He says the report recommends more police training to reduce possibilities for bias. And he says it suggests more data collection on the frequency of police interactions.

Obama spoke from the White House during a meeting with members of the task force.

TROY, Ohio (AP) — A third child has died after being found in an Ohio home where there were high levels of carbon monoxide.

13-year-old Jakia Jones died Sunday.

Her cousins 14-year-old Dionanna Bishop and 13-year-old Dejah Bishop died Friday after a relative found them unconscious inside a home in Troy. Her 8-year-old brother, Jahari Jones, is in critical condition.

Police say a furnace caused the leak of carbon monoxide, an odorless and colorless gas created when some fuels are burned. The relative reported to police the children had been sick for days. The children lived with their grandmother, who was hospitalized with pneumonia Friday.

An attorney for a couple who own the home says they weren’t aware of furnace problems and didn’t know children lived there.

SAN DIEGO (AP) — Federal authorities have seized more than 15 tons of marijuana in a near-record bust at a border crossing in Southern California.

More than 1,200 packages of marijuana valued at nearly $19 million were seized this week from a truck-trailer carrying mattresses and cushions at the Otay Mesa border crossing.

Authorities arrested the truck’s 46-year-old driver and seized the vehicle late Thursday.

The newspaper says the seizure was the second-largest in a single incident at a U.S. border crossing, trailing a more than 35,000-pound bust in 2013.
