One person is in custody and two others are being sought in connection with what Story County Sheriff Paul Fitzgerald described Friday as a “heinous” home invasion and assault last August.

Fitzgerald announced Friday during a news conference at the county administration building in Nevada that charges in the Aug. 23, 2018, attack had been filed.

Jacob Jimenez, Manuel Balderas and Luis Cruz have each been charged with first-degree sexual abuse, first-degree burglary, first-degree robbery, willful injury, two counts of second-degree theft and operating a motor vehicle without owner's consent.

Cruz was taken into custody in Eagle Pass, Texas, and the process has begun to extradite him to Iowa, Story County Attorney Jessica Reynolds said during the news conference.

“We had information that the suspect was in Texas and we utilized the U.S. Marshal's Service to secure his arrest,” Reynolds aid.

Jimenez and Balderas remain at-large and are being sought, and authorities are seeking the public's help in finding them, Reynolds said.

“We do believe they are in our area and asking people to be vigilant, make sure you don't approach the defendants and if you know their whereabouts you immediately call 911,” she said.

She said Jimenez is a suspect in other crimes in the area, and that information received by investigators indicates he was seen in the Ames area as recently as Thursday night.

Fitzgerald said the three men are accused of entering a home in Kelley at about 11:40 p.m. on Thursday, Aug. 23. An 82-year-old woman reported she was confronted by three men who entered her home uninvited and assaulted her, Fitzgerald said.

He said the woman was sprayed in the face with a chemical substance, causing her to temporarily lose her sight. She was also struck on the head and face, and was sexually assaulted, Fitzgerald said.

The men also took property valued in excess of $1,000 from the woman's home, the sheriff said.

He also said the men then went to a second home in Kelley where they are accused of stealing property in excess of $1,500, and a 1998 Cadillac DeVille. The car was recovered the following day.

Fitzgerald gave a message to the defendants and “any other individual who commits such a heinous act.”

“We share with the citizens of Story County a great deal of pride in our communities and will not accept such acts to take place without holding those who perpetrated these acts accountable,” Fitzgerald said. “To Manuel Balderas and Jacob Jimenez, we will bring to those individuals the full weight of our resources to bring them into custody.”
