Wanted posters bearing the picture of a missing 19-year-old Santa Clarita woman, last seen while leaving a New Year's Eve party, were taped to poles in the Santa Clarita Valley on Saturday.

Sarah Katlyn Alarid was last seen at 3 a.m. Tuesday morning, as she had a spat with an ex-boyfriend and left in her car. The party was in the Shadow

Pines neighborhood of Canyon Country, at a friend's house on Poppy Meadow Street. Also missing was her 2002 silver Ford Focus, with a red breast cancer window sticker and California license plates 4WXE747.

A deputy at the sheriff's Santa Clarita station said Saturday the case has been transferred to the sheriff's Homicide Bureau, a common procedure for all missing adults.

Homicide detectives could not be reached for comment Saturday. But on Friday night, detectives were assisted in the search by the sheriff's Santa Clarita Valley Station Search and Rescue Team and the sheriff's Aero Bureau, Deputy Kim Manatt of the Sheriff's Headquarters Bureau said.

That same night, while officials continued their searc, friends pasted the handbills on poles. The former boyfriend is assisting Alarid's parents in the search, according to CBS2.

"It's not like her to run off,'' Amanda Angle of Canyon Country, a woman helping in the search told The Santa Clarita Valley Signal newspaper.

Alarid was described as white and Latino, and is 5-feet 4-inches tall, weighs about 115 pounds and has green-gray eyes and reddish-brown hair.

"She's my youngest daughter and I need her home,'' Laura Alarid, the teen's distraught mother, told CBS2.

Volunteers have been distributing fliers in the area where Alarid disappeared asking for information that could help locate her.

"She's always called, we've always known where she's at,'' her father Mike Alarid, a 30-year veteran firefighter, told CBS2.

Anyone with information about Alarid's whereabouts was asked to call sheriff's Detective Tammy Abraham at (323) 890-5502.
