A state appeals court panel Wednesday upheld a Long Beach man’s conviction for gunning down the mother of his three children in her Bellflower apartment.

The three-justice panel from California’s 2nd District Court of Appeal found “overwhelming” evidence of Antowan Ladell Parker’s guilt in the Jan. 16, 2017, killing of Kenia Buckner.

“Multiple witnesses saw Parker shoot and kill Buckner before walking away. Parker apologized to his son after the murder and disposed of the weapon in his son’s presence,” the appellate court panel noted in its 14-page ruling.

Jurors found Parker guilty in March 2019 of one count each of first-degree murder, assault with a semi-automatic firearm and possession of a firearm by a felon.

Jurors also found true an allegation that Parker personally and intentionally discharged a firearm.

Parker barged into Buckner’s apartment in the 16200 block of Cornuta Avenue with a gun, “told everyone to back off” and pointed a gun at her before shooting the 31-year-old victim six times, according to Deputy District Attorney Steven Schreiner.

The couple’s 9-year-old daughter heard screaming, went upstairs, looked through a window and witnessed the shooting, the prosecutor said.

Parker—who was convicted in 2010 of burglary at a Long Beach apartment where Buckner lived seven years to the day before the killing—was at large until his arrest about three months later, Schreiner said.

Authorities believe the killing was motivated by jealousy after Buckner—with whom Parker had an off-and-on relationship—developed a relationship with another man, according to the deputy district attorney.

Parker was sentenced in May 2019 to nearly 93 years to life in state prison.
