Kailee’s ex-boyfriend Paul Sargent testified that she called him crying in April 2017, three months before her passing.
‘She told me that earlier in the night her mother had pulled a gun on her father after he had slapped her and she had gone to bed with her mother,’ Sargent testified. ‘While she was sleeping with her mom her dad slid in behind her and started trying to touch her inappropriately … and she slid forward against her mom’s back.’
Another friend, Maegan Swan, described Kailee’s relationship with Ronald as that of two friends, rather than a parent and a child, and said that they were drinking buddies.

Swan also repeated the same story about how Ronald allegedly slapped Kailee in the face during a heated exchange, how her nurse mom allegedly pulled a gun on him and threatened to kill him if he touched her daughter again, and how the dad later slipped into their bed and allegedly fondled the 22-year-old.

She also said she does not think Ronald killed Kailee.
In his opening statement on Tuesday, defense attorney Michael Johnson said the woman shot herself and that gunshot residue on her hand supports that theory.
‘Ronald McMullen had no gunshot residue on his hand, not one speck,’ Johnson said.
Prosecutor Jacobi Whatley disputed that theory, saying that evidence presented at trial will demonstrate that ‘Kailee did not fire that gun at herself.’
A Norman police officer testified that Ronald McMullen moved his daughter’s body from the kitchen to the living room and called his wife, Karen, telling her, ‘Kailee’s been shot,’ before calling 911.
Norman police Lt. Chris Vinson says he was immediately suspicious that Ronald McMullen was involved, in part because he was drenched in his daughter’s blood and let his wife answer questions for him.

Johnson countered by saying that there was blood on his client because he was standing close to Kailee when she shot herself.
According to an affidavit for a search warrant filed on July 6, 2017, a day after Ronald’s arrest on murder charges, police arrived at the home on the 1700 block of Abe Martin Drive, to find McMullen’s wife, Karen Hooker McMullan, giving the young woman CPR.

Kailee’s body was in the home’s entryway, and a blood-splattered .357 revolver was found on a side table.
Her father was also covered in blood, and stared blankly when the police asked what happened, cops claim.
When police ventured further into the home they found that McMullen had been trying to mop up blood in the home’s kitchen, the affidavit said.
And when they tried to take pictures of the blood-drenched dad he attempted to wipe it off himself with a towel despite repeated demands that he stop, it alleged.
The towel was snatched away from McMullen, who then tried to use his hands until he was physically restrained, the report said.

After the photos were taken, McMullen’s behavior reached bizarre extremes, as the man allegedly went to the entryway of the home, which borders a grassy front lawn, and ‘lay down in the dirt,’
He then ‘began covering himself in dirt while rubbing the shoes he was wearing on the concrete entryway,’ the affidavit claimed.
Kailee graduated from Norman High School in 2013 where she was a Varsity cheerleading captain, before attending Bible college in Baton Rouge, Louisiana. She was working as an EMT and at a plasma donation clinic in Norman when she was killed.
