BOSTON -- A Malden man remains behind bars tonight, accused of killing his infant son. Prosecutors say the baby's injuries are consistent with shaken baby syndrome.

Much has been made of the fact that the suspect, Geoffrey Wilson, was an alum and employee at Massachusetts Institute of Technology.

"It doesn't matter if you have a lot of degrees or are unemployed. An infant's inconsolable crying -- when you can't seem to help the child resolve it -- can be extremely frustrating," the Massachusetts Shaken Baby Prevention Center Director Jetta Bernier said.

Prosecutors said the 6-month-old's injuries were consistent with extremely violent shaking. Wilson told police he was trying to soothe the baby by shaking him gently to simulate the motion of a car.

But Bernier said that's not what they typically see.

"It's violent. We're talking about very violent behavior and it can last from five to 30 seconds. It's a very serious shaking of a child," Bernier said.

The Department of Public Health and advocates are now giving parents brochures in the hospital to make sure they know the right way to soothe a baby.

Popular techniques involve the so called 5 S's -- swaddling, side or stomach position, swinging, sucking and shushing.

"I'm not talking about a simple little shush but rather shush. Shush louder than the baby is crying," Bernier said.

Advocates hope educating parents will prevent future tragedies.
