“This is an active traffic investigation but I can say that visibility may be a factor in the case,” San Leandro police Lt. Isaac Benabou said in a statement.

Benabou said, “It is dark in those early morning hours but in today’s case visibility was even more restricted due to the fog. Our sincere condolences go out to the victim and everyone involved in this tragic accident.”

Police said they weren’t releasing the woman’s name at this time pending the notification of her next of kin.

The vehicle driver remained at the scene and is cooperating with investigators, according to police.
