Authorities have taken to the air in the search for missing woman Rachel Cyriacks.
State officials confirm they sent a helicopter up Thursday afternoon in the Wessington Springs and Woonsocket areas to search for the 30-year-old.
Cyriacks disappeared last November after working a temporary job in Mitchell, South Dakota.
The Sanborn County Sheriff talked to her husband Bradley Cyriacks back in December, but at the time he was not considered a suspect.
A protection order filed by Rachel Cyriacks in August alleged domestic abuse in the relationship and said the couple was in the middle of a divorce
In January, authorities seized a silver Chevrolet c1500 pickup with damage to the undercarriage they said is related to the case.
Anyone with information on the case is asked to call the Sanborn County Sheriff or Huron Police.
