SAN FERNANDO — A Newhall man was charged today with murder and other counts for allegedly sexually assaulting and killing his 19-day-old daughter, whose body was found in the cab of a pickup in Santa Clarita.

Matthew Brendan Warner, 30, is scheduled to arraigned Feb. 18 in San Fernando in connection with the death of his daughter, Ellorah.

Warner was charged with murder, assault on a child causing death, torture, oral copulation or sexual penetration with a child aged 10 or younger and aggravated sexual assault of a child.

The infant’s body was found Saturday morning in the front cab of a Nissan pickup in an apartment complex parking lot in the 23600 block of Newhall Avenue. She had been reported missing when the father and mother walked in to the sheriff’s station in Santa Clarita at about 9:30 p.m. Friday.

Police dogs, deputies on foot and helicopter crews began an extensive search in the area near the unmarried couple’s condo, in the southern end of Newhall.

But at 7:30 a.m. Saturday, Warner led investigators to the older-model Nissan truck, which was parked about a half-mile from the condo. Three-week-old Ellorah was pronounced dead at the scene, according to the Sheriff’s Information Bureau.

Warner is being held on $2.25 million. He faces up to life in prison if convicted, according to the District Attorney’s Office.
