(STMW) — Miata Phelan’s rage was sparked when she found out her boyfriend brought gifts for his cousin and brother but not for her, Cook County prosecutors said.

And before it was over, the Columbia College student’s anger boiled over to the point where she allegedly stabbed Larry Martin, the Sun-Times is reporting.

Standing over Martin’s body, Phelan — who is seven months pregnant with Martin’s child — screamed as his 8-year-old son looked on: “This is what you get for messing with me. I hope you die, motherf—–,” Assistant State’s Attorney Glen Runk said.

Martin, 28, died Wednesday night near the couple’s apartment in the 6800 block of South Talman Avenue.

“His last words was to me,” Martin’s son, Lavelle, told the Sun-Times on Thursday. “He said, ‘I’m gonna die, but I love you.’ ”

Earlier Wednesday, Phelan, Martin, Martin’s cousin and son went to the mall, Runk said.

When Phelan, 24, learned Martin did not buy anything for her, she accused him of being “selfish,” Runk said. Phelan’s birthday was on Thursday, court records show.

Phelan was so irate that Martin didn’t buy her anything, she allegedly ended up hitting Martin in the car, almost causing an accident.

Phelan kicked and scratched him when he went to drop off some shoes for his brother, Runk said.

Then she drove off with the car, leaving the three others to walk back, Runk said.

Phelan argued with Martin a bit more at the apartment but then she locked him, his cousin and Lavelle out, Runk said.

Phelan let Martin in after he banged on the door, but then she allegedly stabbed him in the side as Lavelle watched.

The cousin escorted Martin out, applying pressure to his wound.

Martin collapsed on the sidewalk.

Judge Maria Kuriakos Ciesil ordered Phelan held in lieu of $1 million bail Friday.

Phelan is eight classes away from receiving her bachelor’s degree at Columbia College and she previously worked as a nurse’s assistant, an assistant public defender said.

Phelan, who wore pink pants in court, had scratches and a swollen face, the defense attorney noted.
