INDIANAPOLIS (AP) — The family of a pregnant teller shot in a bank robbery mourned the loss of the twins she was carrying, while police continued their search for the gunman Friday.

Katherin Shuffield, who was five months pregnant, was critically wounded when a masked gunman shot her in the abdomen Tuesday morning at a Huntington Bank branch. Authorities and the family had said the bullet had not hit the twins.

But complications had set in, and one twin was born dead and the other died after birth, said Marion County's chief deputy coroner, Alfarena Ballew.

Shuffield's husband, Jason, said in a statement that the twins died late Thursday night and that his 30-year-old wife remained in critical but stable condition at Methodist Hospital.

"Katherin's recovery is our top priority," he said.

Shuffield's mother, a Peru native, was granted a tourist visa from the U.S. Embassy and is comforting her daughter "during this very difficult time," the statement said.

Huntington Bancshares issued a statement Friday expressing its sorrow and said it was working with Crime Stoppers on a reward for information leading to the gunman's arrest.

Ballew said that she will examine both fetuses to determine the cause of death.

Prosecutors could consider additional charges, such as feticide, against the gunman because the fetuses have died, said Marion County chief trial prosecutor David Wyser. In order for manslaughter charges to be filed in Indiana, Shuffield would have had to have been at least seven months pregnant, he said.

Meanwhile, police on Friday released three men arrested in connection with the robbery because a story told to them by a suspect turned out to be untrue.

Several details that 25-year-old Shed James Jr. told police were inaccurate, authorities said.

"He flat-out lied," Wyser said.

Wyser said James would be charged with false reporting.

Authorities are looking for new leads after James' account was discredited. Wyser said police do not want to hold the wrong people for the crime, but acknowledged that the false story was a setback for officers searching for the gunman.

"They could have been out looking for the right individuals," he said.

Police were questioning a man in connection with a car that was found Friday similar to one that was believed to have been used in the robbery, said police spokesman Sgt. Paul Thompson. He said the man was arrested on drug charges and he declined to identify him as a suspect in the shooting.

Police also were investigating a similar car that was found Thursday.

According to a police report, an anonymous caller told authorities Tuesday evening that James had been talking about the robbery. Located by police, James said he helped plan the crime and identified other suspects. But he said he changed his mind about taking part while helping check out the bank and asked to be let out of the car.

In his account, James had described actions of the supposed gunman but said he did not know the man's full name.

Police later found details of the story were incorrect and James recanted his story, Wyser said.

Police Lt. Jeff Duhamell called the false report a "bump in the road" of the investigation.

"We've got to keep on going until we know we've got the right people," he said.

Police and the Shuffield family encouraged anyone with information about the case to contact authorities.
