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.

DES MOINES, Iowa (AP) — Dr. Ben Carson is appealing to Iowa conservatives with messages about securing the country’s borders and cracking down on employers who hire immigrants illegally. The retired neurosurgeon called for a harder tack on immigration, expanded school choice and less government spending in his speech Saturday to an Iowa gathering showcasing potential 2016 White House candidates. Carson spoke extemporaneously as he roamed the stage.

Carson is a former physician at The Johns Hopkins Hospital in Baltimore and author who is considering a run for the Republican presidential nomination. He has a following among conservatives for his harsh critiques of President Barack Obama’s health insurance law.

He told the crowd that he’s vehemently against the federal government diving further into health care. “Even if it worked,” he said, he would oppose it.

DES MOINES, Iowa (AP) — Wisconsin Gov. Scott Walker is holding up his “go big and go bold” attitude as something Republicans need to emulate in Washington. In a speech to Iowa conservatives Saturday, Walker ran through a litany of changes he’s implemented that curtailed union power, relaxed teacher tenure laws, strengthened gun rights and restricted abortions. All resonated with a Freedom Summit crowd sizing up potential 2016 GOP presidential candidates like him.

Walker shared stories of staring down union interests in the face of mass protests, constant jeering and even death threats to him and his family. He fought off a recall attempt and then won re-election last fall. The neighboring state governor drew connections to the leadoff caucus state, noting how he attended elementary school in Iowa until his family moved.

DES MOINES, Iowa (AP) — Iowa Sen. Joni Ernst has followed up a national turn in the spotlight with a speech to home-state conservatives that stressed a need to rein in “executive overreach.” The freshman Republican appeared Saturday at a daylong forum attended by several potential 2016 White House contenders. The Freedom Summit was billed at the start of the Iowa presidential caucus chase.

Ernst has enjoyed celebrity status within GOP circles since winning a long-held Democratic seat in November. Just this week, she delivered the party’s televised response to President Barack Obama’s State of the Union address. Ernst revisited themes from that speech, including calls to fight Obama’s executive orders on issues like immigration and pass Keystone XL oil pipeline legislation that the president has vowed to veto.
