A Big Island father is facing manslaughter charges after police say he violently shook and then smothered his three-month-old son until the baby stopped crying, leading to the infant's death.

Investigators say Joshua Paiva, 20, admitted that in late October he aggressively rocked his son in a baby bouncer so hard that the infant's head and body were slammed against the frame, doing this for about 15 minutes because the baby would not stop crying while he played a video game.

He then told police he placed the baby on an ottoman and pressed his body weight down on him until the crying stopped. An autopsy found the baby died from head injuries.

Court records show Paiva initially lied to police, claiming the baby had become unresponsive after spitting up milk, before the true account emerged. Authorities say the case has been difficult for everyone involved, including first responders and medical staff who treated the infant.

Outlook: Paiva now faces manslaughter charges, and the case is expected to move forward through the Hawaii court system.
