Dad ‘killed his 5 month-old son by deliberately dropping baby on his head because he wouldn’t sleep’

A DAD killed his baby son by dropping him on his head because he wouldn’t fall sleep, it is alleged.

Matthew Hoisser, 35, has been charged with second degree murder after his five-month-old boy Gus suffered fatal head injuries including a cracked skull while in his care.

Hoisser told investigators in Minnesota he grew frustrated with Gus for crying and being “difficult” and “fussy”, according to documents from Washington Country court.

“At one point, (Hoisser) was so frustrated he intentionally dropped the infant head first into the ground … intentionally causing him to fall to the ground and strike his head on the floor stunning (the baby) and causing him to continue to cry,” the complaint reads.

The boy’s mother said her son was “noticeably whining and whimpering” and would not take a bottle, USA Today reported.

She took him to his childcare provider around 7am the next day, noting that he hadn’t eaten much and was “fussier than usual.”

The provider reportedly found Gus “limp and quiet” when she went to change his nappy and called 911.

Gus was rushed to the Children’s Hospital in Minneapolis and died five days later from blunt force trauma, The Pioneer Press reported.

Doctors said the injury was so severe that the baby would have been permanently blind, deaf and unable to move if he had survived.

The examiner conducting the baby’s autopsy also discovered evidence of a prior head injury, “likely a week or two within the infant’s hospitalisation”.

Gus Hoisser died on April 30, according to his obituary, which described him as a “source of joy” for his parents and all who knew him.

“He loved riding on his daddy’s shoulder and hearing his mommy sing, especially Rainbow Connection, and will always remain their precious Snuggamonkey,” his obituary read.

Hoisser, who told a judge he has worked at a beer distributor for the past six years, made his initial court appearance on Friday.

A judge has set his bail at $350,000 (£290,000).

The Pioneer Press also reported he was ordered to stay away from his wife, Nicole, who is ten weeks pregnant.

But his lawyer, John Leunig, claimed the measure was unnecessary, saying his wife was “totally supportive” of him.
