On February 26, 2019, 51-year-old Evansville firefighter Robert "Robbie" Doerr was ambushed and shot to death in his driveway after returning home from a 12-hour shift. Investigators determined he had been struck by .45 Colt and .410 buckshot ammunition, consistent with a Taurus Judge revolver. Robbie's wife, Elizabeth Joanne "Becky" Fox-Doerr, called 911 claiming she was cooking inside when she heard gunshots. Investigators discovered Becky received a five-minute phone call from Larry Richmond Sr.—a convicted murderer dating Becky's sister—just minutes prior to the shooting and immediately deleted the call log. Richmond's son admitted to stealing a Taurus Judge revolver from a pawn shop and handing it to his father. Cell phone site data placed Richmond near the crime scene with his phone turned off during the exact timeframe of the murder. In May 2024, Becky Fox-Doerr was convicted of murder and conspiracy to commit murder, receiving a 90-year prison sentence. Larry Richmond Sr. faces trial in May 2025.

Woman Convicted of Husband's Murder After Deleting One Phone Call | Becky Fox-Doerr Case Analysis
Infidelity
The case reflects an extramarital conspiracy where an unfaithful spouse alleged to have collaborated with a romantic partner to eliminate her husband. The victim had previously documented suspicions of his wife's infidelity in a personal letter. Following the ambush, the offending spouse manipulated phone records and offered contradictory accounts to police to obscure her involvement.
Police analyzed physical ballistic evidence, cell tower site data, deleted digital records, and surveillance video to piece together the conspiracy. Becky Fox-Doerr was convicted of murder and conspiracy in May 2024 and sentenced to 90 years in prison on July 17, 2024. Larry Richmond Sr. remains charged with murder and is scheduled for trial in May 2025.
Initial investigative hurdles stemmed from a lack of direct eyewitnesses and Becky's initial denial of communications with Larry Richmond Sr. Discrepancies in witness testimony, including mistaken timelines provided by Larry Richmond Jr., created early narrative inconsistencies that required cell phone forensics to clarify.
Forensics revealed that Larry Richmond Sr. turned off his cell phone near the victim's house around the time of the ambush and made a five-minute call to Becky Doerr right before the shooting. Becky deleted the phone call entry immediately after concluding it. Autopsy findings confirmed the victim was struck by projectiles uniquely matching a Taurus Judge revolver previously acquired by Richmond Sr.
Key risk indicators included prior serious violent offending by the co-conspirator, active romantic deception, concealed communication patterns, and unaddressed domestic tension surrounding suspected infidelity. The presence of a felony record and illegal firearm acquisition significantly elevated the lethality threat.
Digital forensic recovery of deleted call logs and cell tower location mapping served as critical evidence in exposing a premeditated spousal murder conspiracy, highlighting how digital concealment often leaves recoverable forensic trails.
Robbie Doerr documented signs of emotional distance and discovered hidden text messages from another man on Becky's phone prior to the incident.
A deleted five-minute call on Becky's phone received minutes before the gunshots and photo evidence of a Taurus Judge revolver on Larry Richmond Jr.'s phone connected the co-conspirators.
Cell phone location records, gas station surveillance footage, deleted call logs, and ballistics matching a Taurus Judge revolver provided the core evidentiary framework.
Neighbors reported hearing five gunshots near the victim's residence. Becky Doerr claimed she was cooking in the kitchen when she heard popping noises outside.
Subsequent cell phone location analysis in June 2021 proved Larry Richmond Sr. was in the immediate vicinity of the crime scene and was utilizing a police scanner app before and after the shooting.
Larry Richmond Sr.'s trial is pending for May 2025, and Becky Fox-Doerr continues to maintain her innocence despite her conviction.
