They also called dozens of witnesses, including his former mistress Alleigha Botner, whom he met while she was an intern at his church.
Some of their 100,000 exchanged text messages were read aloud in court. The defence called no witnesses.
“I was up until 4am last night crying, literally thinking of ways to kill her and not go to jail,” Flynn wrote in a message to Botner, 24, in August 2025.
In another message, he wrote: “I just want her dead and gone.”
Testifying in court, Botner said she now hates Flynn “because I believe that he murdered his wife”.
During closing arguments on Tuesday, prosecuting attorney Paul Watkins leaned heavily into Flynn’s text exchanges, which he said demonstrated the defendant’s “hatred” for his wife.
He described Flynn as being afraid to lose custody of his daughters in a divorce, as well as his job with his wife’s family business and his job at the church.
An emotional Flynn was seen in court at times sniffling and wiping tears from his eyes.
Watkins also said that when police arrived at the family home in the early hours on 16 February, Flynn told police he had been in his daughters’ bedroom when he heard gunfire.
Flynn said he found his 37-year-old wife dead in the bedroom, after noticing the garage side door was open. Watkins said Flynn later told investigators he had not been to the garage, contradicting his earlier statement.
Flynn’s defence lawyer Patrick Mulligan, meanwhile, told the court there was no concrete evidence, saying: “Connecting a couple of meaningless dots doesn’t solve the case.”
Mulligan said the issue was not whether Flynn was a good husband to his wife, a schoolteacher and volleyball coach, and that evidence of infidelity was not evidence of murder.
“They can’t find the gun, therefore they blame it on him?” Mulligan questioned, referring to the charge of tampering with evidence that Flynn also faced.
Flynn’s gun, which had been kept in the console of his truck, has been missing since investigators arrived at the scene and found the truck’s centre console open.
Earlier in the trial, Botner took the stand as a witness for two days, offering testimony about her nearly 18-month relationship with Flynn.
