COUNCIL BLUFFS, Iowa (AP) – Police are looking for a man involved in a crash that caused a Council Bluffs house fire. The Daily Nonpareil reports that a man was driving a 2004 Chevy Silverado pickup just after 2 a.m. Friday when he crashed into the home’s porch. Witnesses told police the driver fled on foot. No injuries were reported.

Council Bluffs police say the truck caught fire after the wreck and was engulfed in flames by the time officers arrived. The fire spread to the porch, but the house was not damaged. Assistant Fire Chief Matt Thomas says the wreck caused an estimated $15,000 in damage.

Police Sgt. Jason Bailey says the department hasn’t been able to contact the pickup’s registered owner.

SIOUX CITY, Iowa (AP) — A federal judge in Iowa says a man sentenced to life in prison for two robberies is one of the most dangerous people he’s ever seen. The Sioux City Journal reports that U.S. District Judge Mark Bennett made the comment at 23-year-old Jamal Dean’s sentencing on Friday.

Authorities say Dean, of Sioux City, has a criminal record stretching back to age 7. In August, he was found guilty of conspiracy, weapons, carjacking and robbery charges in connection with separate robberies of drug dealers in April 2013. He also pleaded guilty to an attempted murder charge in state court after he shot a police officer in the head.

Bennett says he believes in second chances, but described Dean as one of the biggest threats to society he’s ever seen.

COLLEGE SPRINGS, Iowa (AP) — Authorities say two family dogs that fatally mauled a 7-year-old College Springs boy have been euthanized. Malaki Mildward, a first-grader, died shortly after the attack Thursday afternoon. Page County Sheriff Lyle Palmer tells the Omaha World-Herald that the dogs were 6-month-old puppies — a 25-pound female and a 35-pound male. Palmer says the dogs were mixed-breeds with some bulldog heritage and had shown no signs of aggression.

Palmer said the boy’s family also euthanized another family dog — a bulldog mix who was not involved in the attack on the boy. Authorities believe Malaki went outside to play with the puppies, as he often did, when he was mauled. No one witnessed the attack.
