LAKEWOOD, N.J. (WPVI) -- A New Jersey man entered a guilty plea Thursday in connection with the death of his infant daughter.

Ruben Santiago, 36, of Lakewood, pleaded guilty to aggravated manslaughter.

The 3-month-old died back in May. Authorities determined her cause of death was blunt force trauma to the head.

Santiago and the girl's mother, Caitlin Gibson, were arrested.

The charges against Gibson remain pending.

Prosecutors are asking that Santiago serve 25 years in prison, without early release.

He's due to be sentenced in March.
