DELPHI, Ind. — Richard Allen’s defense team rested its case after calling 20 witnesses to the stand Wednesday.

It’s the 17th day of the double-murder trial for Allen, who is accused of killing Libby German and Abby Williams.

The girls were killed in February 2017 while walking along the Monon High Bridge.

The defense remained shortly after the court was called to order.

They spent most of their time questioning the state’s case against Allen, questioning the quality of the crime investigation, the science used in the case and the forensics presented to the jury.

On Tuesday, attorneys aggressively sought to cast doubt on the state’s argument that Allen killed the girls.

Former FBI forensic examiner Stacy Eldridge was the 21st defense witness to testify. She told the court she spent 65 hours reviewing digital information in the case.

Eldridge’s testimony agreed with several aspects of what state police experts said they found. She criticized investigators for not doing a better job of pulling data from German’s phone, which could have led to better findings.

The highlight of her testimony came when Eldridge said at 5:45 p.m. on Feb. 13, 2017, a phone call came into Libby’s phone and within “milliseconds” a headphone jack was inserted.

Eldridge went on to say that the headphone jack was removed nearly five hours later at 10:32 p.m. She said: “I can’t think of any explanation that doesn’t involve human interaction.”

Prosecutor Nick McLeland questioned whether plugging in a headset would have caused the phone to record movement.

Elridge replied, “It might; it was not possible”.

He continued by asking if the phone would record movement if it was picked up and carried through the woods. She replied, “Yes.”

Eldridge also acknowledged that there is no record that the phone was ever turned off.

Jurors had several questions, including whether Eldridge ever created his own timeline using data from German’s phone. She replied, “No.”

Another juror asked if Eldridge could tell if the phone was on silent or vibrating. She said she didn’t know.

Eldridge was then asked if water or moisture on the phone could be recorded as motion.

She also said she didn’t know.

State police experts Brian Bunner and Chris Cecil were called back to the stand. The defense pressed them on their lack of reporting on the headphone jack data.

Cecil responded by saying he had Googled the jurors’ question about water or moisture on the phone. He said he read that a headphone jack can register as used if there is water or dirt in the port.

The defense quickly countered by asking Cecil, “Do you usually Google when you’re doing research in a criminal investigation?”

Cecil replied with “not normally, no”. He said he normally uses peer-reviewed research.

Defense attorney Jennifer Auger then pressed further, saying, “You and the state had seven and a half years to investigate?”

Cecil replied, “That’s right.”

Auger then said, “and you came here with a google search?”

Cecil said, “That’s right.
