The Ashley Flynn case took a major turn this week as Alleigha Botner, the former mistress of Caleb Flynn, testified about their affair, an ultimatum she gave him, and disturbing statements he allegedly made about his wife before Ashley was fatally shot.
Botner testified Wednesday, September 23, during Flynn’s ongoing murder trial in Miami County, Ohio. She told jurors that she and Flynn had exchanged more than 100,000 messages during their relationship and that he repeatedly spoke about wanting Ashley dead.
Flynn, 40, has pleaded not guilty to aggravated murder, murder, felonious assault, tampering with evidence and witness intimidation charges connected to Ashley’s February death.
Prosecutors allege Flynn shot Ashley inside their Tipp City home on February 16, 2026, while their two daughters were in the house. They also allege that he manipulated the scene to make the killing appear to be the work of an intruder.
The defense disputes the prosecution’s interpretation of the evidence and has argued that Flynn’s affair and private statements do not prove that he killed his wife.
Who Is Alleigha Botner in the Ashley Flynn Case?
Alleigha Botner, 24, is a central prosecution witness in the trial because of her relationship with Flynn and the large volume of messages exchanged between them.
Botner testified that she met Flynn through the church community where they were involved. Their relationship initially remained professional, but she said it became personal in 2024 and eventually turned sexual.
She knew Flynn was married to Ashley when the relationship became intimate. During testimony, Botner acknowledged that she understood the affair was wrong.
The relationship continued for roughly a year and a half, according to her testimony. During that period, she said she and Flynn exchanged approximately 107,000 messages.
Many of those messages became important evidence for prosecutors.
Botner told jurors that Flynn regularly complained about Ashley and repeatedly talked about wanting her gone. She said those comments became increasingly disturbing as the relationship continued.
She also testified that Flynn told her Ashley had previously been unfaithful. Botner said Flynn described his marriage as unhappy and portrayed himself as remaining in the relationship partly because of their children.
Those claims are part of Flynn’s account as described through Botner’s testimony. They have not established that Ashley was unfaithful.
Botner Says She Gave Flynn an Ultimatum
One of the most significant details from Botner’s testimony involved an ultimatum she said she gave Flynn before Ashley’s death.
Botner testified that she eventually became frustrated with Flynn’s repeated promises to leave his wife. She said she gave him a final deadline in January.
Her message to him was essentially that he needed to leave Ashley or she would move on with her own life.
Botner testified that Flynn did not leave his wife by the deadline.
She then stopped communicating with him for a period.
The relationship resumed around Valentine’s Day, February 14, just two days before Ashley was killed.
According to Botner, Flynn told her that he was finally going to leave Ashley and proceed with a divorce. She said he also told her that he had spoken with Ashley about ending the marriage.
That conversation became particularly significant because of what happened two days later.
What Flynn Allegedly Told Botner Before Ashley’s Death
Prosecutors have placed considerable attention on messages Flynn allegedly sent Botner shortly before Ashley was killed.
Botner testified that Flynn told her he was finally choosing her and would be free of his marriage.
One message prosecutors presented in court said:
“I choose you. I’m free. Actions will come tomorrow.”
The message was sent late on February 15, according to testimony and evidence presented at trial.
Botner said she understood the reference to “actions” as meaning Flynn was finally going through with the divorce.
She testified that Flynn had previously told her he intended to speak with Ashley about ending their marriage.
The next day, Ashley was dead.
Botner told jurors that the timing immediately alarmed her.
She said she expected to hear from Flynn after he carried out what she believed was his plan to end the marriage. Instead, she learned that Ashley had been killed.
Botner testified that the situation appeared to be an extraordinary coincidence.
Botner Describes Flynn’s Alleged Comments About Ashley
The prosecution also questioned Botner about comments Flynn allegedly made about Ashley throughout their relationship.
According to her testimony, Flynn repeatedly expressed hatred toward his wife.
Botner said he talked about wanting Ashley gone and, at other times, spoke more directly about her death.
She testified that the comments occurred regularly and became more troubling over time.
Prosecutors also showed jurors messages that they say demonstrate Flynn’s anger toward Ashley.
Among the alleged messages was one in which Flynn reportedly said he had stayed awake thinking about ways to kill Ashley without going to jail.
Another alleged message expressed a desire to kill her if he could avoid punishment.
The prosecution argues that these messages help establish motive and intent.
Flynn’s defense has taken a different position. His attorneys have acknowledged the affair and the existence of hurtful messages but have argued that making disturbing statements does not establish that Flynn committed murder.
That distinction is central to the trial because the jury must determine whether the prosecution has proved the criminal charges beyond a reasonable doubt.
The Affair Was Kept Secret
Botner also described the steps she and Flynn took to conceal their relationship.
She testified that they used multiple messaging platforms and regularly deleted conversations.
The large number of messages made the relationship especially important to investigators.
Botner said they exchanged messages through services including iMessage, WhatsApp and GroupMe.
She also acknowledged that she had deleted communications herself.
During testimony, prosecutors questioned her about efforts to remove digital evidence from devices.
Botner said she had advised Flynn about deleting information from his devices on multiple occasions.
She testified that one such discussion occurred shortly before Ashley’s death.
That testimony has become another point of interest because prosecutors are presenting the digital communications as evidence of the relationship and Flynn’s state of mind.
Botner Admits She Initially Lied to Investigators
Botner’s testimony also included damaging admissions about her own conduct after Ashley’s death.
She acknowledged that she initially lied to the FBI about her relationship with Flynn.
Botner explained that she feared the affair would become public and damage her reputation and employment.
She also testified that she deleted a message she sent Flynn after learning that Ashley had been killed.
According to Botner, she contacted Flynn after learning about the shooting because she was alarmed by the timing.
She said he did not respond.
Botner testified that she deleted her message because she feared investigators would search Flynn’s phone and discover the affair.
Investigators later uncovered evidence of the relationship.
Botner eventually provided more information about the affair after investigators told her they had found messages on Ashley’s phone.
Her initial dishonesty is expected to be an important issue for the defense as the trial continues.
What Happened to Ashley Flynn?
Ashley Flynn, 37, was found fatally shot at the couple’s Tipp City home on February 16.
Flynn called 911 and reported that an intruder had entered the home and shot Ashley.
Police initially responded to what was described as a possible burglary and shooting.
Investigators later questioned that explanation.
Prosecutors now allege that Flynn himself killed Ashley and staged the scene to make it appear that an intruder had entered the residence.
Evidence presented during the trial has included testimony about the condition of the home, the alleged break-in and the search for the firearm investigators believe was used in the killing.
The weapon has not been recovered.
That remains one of the issues highlighted by the defense.
Flynn was arrested three days after Ashley’s death.
He was subsequently indicted on multiple charges, including aggravated murder, murder, felonious assault, tampering with evidence and witness intimidation.
He remains a defendant in an active criminal trial and is presumed innocent unless convicted.
Why the February 15 Message Matters
The message sent shortly before Ashley’s death has become one of the prosecution’s most closely examined pieces of evidence.
Flynn allegedly told Botner that he was free and that “actions” would come the following day.
From the prosecution’s perspective, the message fits into a broader pattern of alleged communications in which Flynn discussed his frustration with Ashley and his desire to be with Botner.
Botner, however, testified that she understood the message differently at the time.
She said she believed Flynn was finally going to divorce Ashley.
That distinction is important.
The prosecution is asking jurors to consider the message alongside the other evidence presented in court. The defense can challenge the meaning of the message and the reliability of the witness describing it.
No verdict has been reached.
Botner Says Her Feelings Toward Flynn Changed
Botner also described how her feelings toward Flynn changed after Ashley’s death.
She testified that she once loved him.
When prosecutors asked how she feels about him now, she gave a very different answer.
Botner said she hates Flynn because she believes he murdered Ashley.
Her testimony does not establish Flynn’s guilt by itself. It represents one witness’s account of the relationship and the statements she says he made.
The jury will ultimately decide what weight to give her testimony after considering the full body of evidence and the defense’s response.
The Trial Remains Ongoing
As of September 24, 2026, the trial is still underway in Miami County.
Botner is expected to return to the witness stand as testimony continues. Prosecutors are also expected to present additional witnesses as they build their case.
The proceedings have focused heavily on the alleged affair, the extensive digital communications between Flynn and Botner, the circumstances surrounding Ashley’s death and the prosecution’s claim that the crime scene was staged.
The defense has challenged the prosecution’s interpretation of the evidence and maintained that the state must prove Flynn committed the killing rather than relying on evidence of marital problems or infidelity.
The outcome remains unresolved.
For readers following the Ashley Flynn case, the most important development now is the continuing courtroom testimony. Botner’s account has given jurors a detailed look at the relationship prosecutors say provides a motive for the killing, while the defense continues to challenge the conclusions drawn from that evidence.
The trial continues, and further testimony could provide additional details about what happened to Ashley Flynn and what role the alleged affair played in the case.
