MURRIETA – The girlfriend of professional skateboarder Neil Heddings was sentenced Friday to 25 years to life in state prison for killing his 2-year-old son.

A jury convicted Christine “Pinky” Rams, 27, of second-degree murder and assault in November 2005.

Coroner's officials determined that Marcus Heddings died in November 2002 as a result of several blows to the head.

Neil Heddings, 31, was convicted of involuntary manslaughter and sentenced to six years in state prison for the death. Prosecutors said he failed to protect his son and prevent the death.

Rams, who did not testify at the trial, on Friday spoke of her frustration with the jury's verdict and her attorney before Riverside County Superior Court Judge Mark Cope sentenced her.

“I want to declare my innocence to the court,” said Rams, who had alleged Marcus suffered his injuries while under the supervision of his mother in San Diego.
