A Delaware judge has rejected a post-sentencing request from a woman who admitted to killing her weightlifter husband by putting antifreeze into his steroid injections.

Jamie Baker was sentenced to 40 years in prison in March after pleading guilty to second-degree murder.

Baker did not file a direct appeal of her sentence, but she did ask last month for more time to file a motion for reduction of sentence.

The judge denied the request late last week, saying it is not permitted under court rules.

Baker admitted poisoning her 42-year-old husband, James Baker, a competitive weightlifter who died in September 2013.

Baker reportedly told officers she filled a hypodermic syringe with antifreeze and injected it into her husband's bottles of liquid steroids, but she did not give them a motive.
