The Great Gatsby, in the wake of her sister's body

I'd like to know if in the following excerpt from the chapter 8 of The Great Gatsby the phrase "in the wake" means "following" or refers to the "funeral vigil":

They had difficulty in locating the sister, Catherine. She must have broken her rule against drinking that night for when she arrived she was stupid with liquor and unable to understand that the ambulance had already gone to Flushing. When they convinced her of this, she immediately fainted, as if that was the intolerable part of the affair. Someone, kind or curious, took her in his car and drove her in the wake of her sister’s body.

Thank you.
