PALMER - A Wasilla man charged with killing his baby daughter has pleaded not guilty.
A Palmer grand jury indicted Clayton Phillip Allison last week on three charges, including second-degree murder. Investigators believe he slapped the girl to death.
Allison was arrested Nov. 17, more than a year after the death.
"Any time there's an investigation where we're looking at cause of death and different kinds of trauma and getting medical results and consulting experts, all of that takes time," said Megan Peters, Alaska State Troopers spokeswoman. "Even fatal wrecks on the highway can take a year easily for charges to be filed. We don't rush into things."
Police were called to Allison's home on Sept. 24, 2008, on a report that the 15-month-old girl had fallen down a flight of stairs. The baby was airlifted to Providence Alaska Medical Center in Anchorage, where she underwent surgery but didn't survive.
According to an affidavit filed by Alaska State Trooper Sherry Ferno, the injuries included blunt force trauma to the head and neck with multiple hemorrhages in various parts of the brain.
"The injuries do not match a fall down 8 carpeted steps," Ferno wrote.
Ferno wrote that a second pair of troopers interviewed Allison months after the incident.
"Clayton initially stated he had done nothing wrong. Later during the interview Clayton said he was slapping his daughter over a period of time, and began striking (her) harder with time," Ferno wrote.
