In July 2012, we told you about the arrest of Marquis Garrison in the death of his two-month-old daughter, as well as the decision to pursue a first-degree-murder charge in addition to a child-abuse-resulting-in-death count. A likely reason: A probable-cause statement on view below says he tried to make the baby stop crying by slamming her to the floor.
Now, a jury has found him guilty of both accusations. Details below.
On June 26 of last year, as we reported, a detective was called to Denver Health Medical Center shortly after a couple arrived with their two-month-old daughter. The girl was soon determined to be in critical condition.
At Denver Health, a pediatrician shared the tale told by the parents -- Garrison, thirty, and an unidentified woman. According to comments synopsized in the report, they stated that the child began vomiting about a week previous, and then started seizing a few days later, after rolling off a bed onto some carpet. The pair allegedly said they hadn't sought medical help for these symptoms or for any other reason since the girl was born the previous April.
Upon learning that her daughter was clinging to life, the statement maintains that the woman went to work. But the pediatrician who spoke to the cop didn't think the parents' story explained the child's severe brain injury. This conclusion was reinforced soon thereafter, the report says, when staffers confirmed a potpourri of other wounds, including broken right and left femurs, a broken left tibia and a broken left shoulder -- damage that would only make sense if that bed from which the child had supposedly fallen was at least three stories tall.
What really happened? In an attempt to find out, the detective called Garrison to police HQ. According to the document, the suspect said the child was crying so persistently on June 25 (the day before she was taken to the hospital) that her mom left the apartment, leaving him in charge. He responded by shaking the baby, but that didn't do the trick. So he began throwing her on the floor next to him -- after which he apparently picked her up and began shaking her again.
Shockingly enough, the baby began to suffer seizures later that day.
Somehow, the child managed to survive this abuse, at least initially. As such, Garrison was charged with child abuse resulting in serious bodily injury. After she died, however, the Denver District Attorney's Office upgraded to first-degree murder and child abuse resulting in death -- and late last week, the DA's office reveals that a jury found him guilty of both.
He's due back in court on November 18. He faces life in prison without parole.
Here's a larger look at Garrison's mug shot, followed by the probable cause statement.
