Man tortures and murders girlfriend's 18-month-old girl because he was "angry" he had to babysit her

It only took 20 minutes for the jury to hand down a unanimous guilty verdict, before Bradley Logan was sentenced to life imprisonment

A man who was frustrated that he had to babysit his girlfriend's 18-month-old child ended up killing the tot out of anger. Bradley William Walter Logan told police he "felt very angry" when his girlfriend left him to take care of her 18-month-old child at their residence in Cairns, Queensland, on January 15, 2007, Daily Mail reports. 

Logan, who was 19 at the time, inflicted severe injuries to the girl in the 20 minutes he was left alone with her. According to reports, he inflicted several blows to the infant's abdomen, swung her by the legs so her head struck a TV set, and even inserted objects in the toddler's body.

The child's mother returned home to find her little girl lying motionless on a bed while her boyfriend sat calmly on the couch in his underwear watching TV.

The critical injuries left the child with a broken face and bruises all over her body. She died from internal bleeding just before midnight after being rushed to Cairns Hospital for immediate medical attention.

Logan later demonstrated to police during an interrogation how he had inflicted at least 18 individual blows on the child. Although he admitted to causing the girl's death, he said he never intended to fatally beat her.

That said, he later pleaded guilty to two counts of rape.

Justice Stanley, who presided over the 2008 court case, described the crime as "'horrific, cruel" and one that caused "revulsion in all right-thinking persons." He told Logan, "And the mother; I don’t think anyone can really understand the pain she will suffer because of your actions."

It only took 20 minutes for the jury to hand down a unanimous guilty verdict, before Logan was sentenced to life imprisonment for the murder charge and eight years each for the rape offenses.

He continues to serve time at the Wolston Correctional Centre in Wacol.
