DELPHI, Ind. — Witness testimony continued into Wednesday afternoon as jurors in the high-profile Delphi murders trial heard from an Indiana State Police digital forensics examiner about data extracted from Libby German's cell phone. Richard Allen faces four counts of murder in connection with the vicious killings of teenage girls Abby Williams and Libby German in February 2017 near the Monon High Bridge in Delphi. He was arrested in October 2022 by Indiana State Police. Richard Allen Mugshot - Oct. 13, 2024 During the fifth day of witness testimony, jurors heard from one of the primary witnesses who spotted "Bridge Guy" on the day the girls went missing. Jurors also saw photographs of the girls' autopsies and heard from the pathologist who conducted the examination. After a lunch break, ISP Sgt. Chris Cecil took the stand to speak about cell phone data extracted and linked to Libby German's cell phone. Libby's cell phone produced the infamous "down the hill" video and audio clip, which was played in its entirety for jurors on Tuesday. During previous family testimony, it was noted Abby Williams did not own a cell phone at the time of her death. Libby's phone ended up being found underneath Abby's dead body. Cecil told jurors on Wednesday that police investigators used cell phone towers to ping Libby German's phone. The girls vanished while walking on the trails near the Monon High Bridge on Feb. 13, 2017. Libby's sister previously testified to dropping the girls off at the trails at around 1:40 p.m. 13-year-old Abby Williams and 14-year-old Libby German.

Two minutes later is the last time Libby's phone would be unlocked. At 2:13.51 p.m., Libby took the infamous "Bridge Guy" video that captures a man walking behind the girls and telling them, "guys, down the hill." At 2:31 p.m., cell phone records note a change in longitude, altitude and elevation. Cecil explained this meant the phone was on the move as the girls were reportedly led down a hill and possibly across Deer Creek. By 2:32.39 p.m., the phone was no longer moving. It never moved again nor did it ever ping anywhere outside the trails, Deer Creek and the site where the girls' bodies would be found on Feb. 14. Cecil told jurors that the phone gradually powered down throughout the night. Originally, Cecil noted in a report that the phone died at 10:32 p.m. But then the phone spiked at 4:34 a.m. and received 15 to 20 text messages all at once including a message sent nearly 12 hours prior (at 4:06 p.m.) by Libby's grandmother that said, "Call me now." Those messages were never answered. Cecil stated he no longer believes the phone died at 10:32 p.m. and called his previous conclusion "premature." Additional information led Cecil to believe the phone stayed on until 4:34 a.m. when it received the numerous text messages. He also noted there was "no indication" that the phone was ever turned off after its last movement near 2:30 p.m. on Feb. 13. When asked about why the phone didn't have any activity between 10:32 p.m. and 4:34 a.m., Cecil said, "I do not know why." Cecil noted the phone was powered on at 3:06 p.m. on Feb. 15 by investigators. While questions remained about the phone's period of inactivity, locator pings never placed the phone outside the Monon High Bridge area and the site near Deer Creek where the girls' bodies — and the phone — were found. This lack of movement casts doubt on the defense team's floated theory of a possible abduction and off-site killing. Andrew Baldwin, one of Allen's defense attorneys, floated the theory early on in the trial. Baldwin theorized a killer could have forced the girls into a vehicle and driven them to another site to murder them before returning and dumping the bodies at the creek bend. But the cell phone data already links the girls to the site where their bodies would be found at 2:33 p.m. A site multiple crime scene investigators noted was "saturated" with pools of blood. The girls were first noted as missing around 3:30 p.m. on Feb. 13 (roughly an hour after the phone quit moving) when Libby's father came to pick the girls up. Their bodies weren't found until shortly after noon on Feb. 14. Testimony moved on from Libby's phone to 23 different devices seized from Richard Allen's possession. But these devices weren't seized until November 2022, five years after the girls' deaths. Nothing linking Allen to Abby or Libby was found on any of these devices, besides searches about the murder investigation. It was noted that Allen had a different phone in 2017, however, that investigators never found. He no longer had that phone when police came calling in 2022 after finding an old report placed Allen on the trails on Feb. 13, 2017, leading police to decide to take a closer look into the man. Testimony will resume on Thursday.
