"John, I f---ing hate you," Karen Read allegedly told her boyfriend, Boston Police Officer John O'Keefe, a minute after walking into his house without him.

It was the morning he died, and she had just driven there from the crime scene, according to Massachusetts investigators.

Special prosecutor Hank Brennan played a series of voicemails that Read allegedly left after authorities said she struck him with an SUV and left him to die in a blizzard.

Massachusetts State Trooper Nicholas Guarino returned to the stand Tuesday to read through text messages and phone calls between Read and O'Keefe from the evening of Jan. 28, 2022, into the following morning, when Read was among three women who found him.

Records show Read's phone connected to the Wi-Fi at O'Keefe's home at 12:36 a.m. on the 29th, Guarino said. Read made more than 50 calls to O'Keefe that morning but did not leave a voicemail every time.

At 12:37 a.m., she left the first of eight voicemails for O'Keefe.

"John, I f---ing hate you," she said, in a recording played in court.
By then, prosecutors allege O'Keefe had been mortally injured by the rear end of Read's Lexus SUV and left for dead as a blizzard picked up strength.
At 12:41 a.m., she left a second voicemail that included no spoken words. Guarino said it may have been a "butt dial."
She texted him twice, "I'm going home," and "see u later."

In a third voicemail at 12:59 a.m., Read said "John, I'm here with your f---ing kids, Nobody knows where the f--- you are, you f---ing pervert."
O'Keefe adopted his niece and nephew after their parents, his sister and brother-in-law, died within months of one another.
A fourth voicemail, left a minute later, was one second long and included no words.
She then texted that she had returned to Mansfield, where she lived at the time, and that his children were "alone."
She appears to have been lying about leaving his house, however.

At 1:10 a.m., she left a fifth voicemail.
"Yeah, it's 1 in the morning. I'm with your f---ing niece and nephew, you f---ing pervert," Read said in a fifth voicemail. "You're a f---ing pervert."
At 1:17 a.m., she accused him of cheating on her with another woman.
"You're a f---ing loser, go f--- yourself," she said.

She stopped calling him between 1:18 a.m. and 4:38 a.m, when unanswered calls picked up again.
Grace Edwards, an Essex County-based criminal defense attorney who has been closely following the case, told Fox News Digital that the calls paint Read as someone who was unaware of O'Keefe's death at the time.
"They are of a hysterical girlfriend, frantic," she said. "She doesn't know what happened."
At 5:23 a.m., she left him a seventh voicemail. She kept calling until leaving an eighth voicemail at 6:03 a.m., around the time Read, Jennifer McCabe and Kerry Roberts found O'Keefe unresponsive outside 34 Fairview Road.

"I think there's a ton of holes in the prosecution," said David Gelman, a Philadelphia-area defense attorney who has been following the case. "Tons of reasonable doubt."
The calls indicate that Read didn't know O'Keefe was dead until she arrived at the scene, which is a boon for the defense, he said.
"Devil's advocate, though, is that she was covering her tracks by doing this and is calculated," he said.
