SAN FRANCISCO (AP) — San Francisco police officers on Monday afternoon arrested a man with Iowa ties described as social media maven and former political consultant who was wanted by federal agents on suspicion of possessing explosives.

The Omaha World-Herald reports authorities in Carroll County are offering a $10,000 reward for information that leads to the successful prosecution of the person responsible for the death of a mother and her adult son a little more than two weeks ago in Glidden.

The bodies of 48-year old Tami DeVore and 30-year old Karl DeVore were found by Carroll County deputies inside the mobile home where Tami DeVore lived., the night of Sunday, May 18th. Authorities have not released how the DeVores died but have said their deaths were the result of homicides. There have been no arrests.

DES MOINES, Iowa (AP) — Rural southwest Iowa state Sen. Joni Ernst has emerged as a front-runner in what once was a jumbled field of Republicans hoping to succeed retiring Democratic U.S. Sen. Tom Harkin. Ernst has managed to bring together warring factions of the state and national GOP before the primary. She has aired ads featuring her firing a handgun at an indoor shooting range and talking about her childhood experience castrating hogs.

Today’s (Tuesday’s) primary is significant because Iowa, a traditional swing state, is expected to play a key role in the race for U.S. Senate control this fall. Republicans need six seats to gain a majority. Neither party will have the power of incumbency in the race. The GOP views Democratic U.S. Rep. Bruce Braley, the assured nominee, as vulnerable.

COUNCIL BLUFFS, Iowa (AP) — A transient was arrested following a brief standoff in Council Bluffs, Monday. The Council Bluffs Police Department says 29-year-old Kevin Richard Bequette was taken into custody at around 10:30-a.m., after the Omaha Metro Fugitive Task Force tracked Bequette to a residence and attempted to apprehend him on a warrant for a parole violation. The man is accused of locking himself inside a detached garage behind the home.

Authorities communicated with Bequette for about 45-minutes, during which he threatened to harm himself. At around 10:30-a.m., officers could smell smoke coming from the garage. They broke into the structure and took Bequette into custody without further incident. Authorities learned the man started a small fire in the garage, and there was evidence he had attempted to compromise a natural gas line inside the building. Damage to the garage was described as minimal.

Police Capt. Todd Weddum says Bequette was checked by medics at the scene, but he did not require any treatment. Weddum said Bequette was arrested for a parole violation related to earlier arson/theft and attempted burglary charges,  in addition to a warrant for 3rd  degree criminal mischief and Interference with official acts.

Bluffs police recovered two stolen cars on the property. Officials say an investigation continues with regard to the vehicles, and additional charges against Bequette are pending.
