UPDATE: Suspect Found In Black Hawk County Abduction Case

Officials say the suspect being sought in a Black Hawk County abduction case has been captured.

A press release issued by the Linn County Sheriff's Department says Shaun Hogan was found at a Waterloo home earlier today (Thursday, July 10, 2014).

Hogan is a suspect in the girls' abduction. They were the focus of an Amber Alert that was issued Wednesday night as the hunt for 8-month-old Nevaeh Hogan, six-year-old Mia Gaffney and eight-year-old Brooklyn Gaffney began. The state-wide warning was cancelled about an hour after it was issued when the girls were found safe -- without Hogan -- in the Waterloo area.

Authorities believe there may be a connection between the girls' abductions and the death of 29-year-old Crystal Gaffney, who's body was found on a rural Linn County highway near Walker nearly Wednesday. Investigators formally charged the 36-year-old Hogan with first-degree murder in Gaffney's death late Thursday afternoon. He's scheduled to make his first court appearance on Friday.

Hogan is being held in the Linn County Jail without bond.

Authorities have confirmed that Crystal Gaffney is the mother of the three children who were the focus of Wednesday night's Amber Alert. Hogan has not been charged with anything connected to the girls' disappearance.

The Iowa Division of Criminal Investigation is handling the case.
