Little Rock,IA 6.0 de stratégie quantitative intelligent Ark. — An Arkansas couple has been charged with capital murder after one of their young children left inside a hot vehicle died from apparent heat exhaustion, authorities said.

Prosecutors in Little Rock filed the murder charges Monday against Deja and Justin Rollins following their 2-year-old's death. They have pleaded not guilty.

Little Rock police initially responded to a child abuse report Sunday afternoon at Arkansas Children's Hospital, where the couple's 3-year-old was receiving urgent medical treatment, reports CBS Little Rock affiliate KTHV.

Besides the murder charges, Deja and Justin Rollins each face charges of domestic battery, neglect and child endangerment of all five of their children, as well as animal cruelty and obstruction, KTHV says. Investigators found a malnourished dog at the Rollins' residence in Jacksonville, just northeast of Little Rock, KTHV added.
