At Tuesday’s press conference, police revealed Ms Kupfer texted a friend expressing concern about someone who had entered the Croft House furniture store.

“She sent a text to a friend letting her know that there was someone inside the location that was giving her a bad vibe,” LAPD Lt John Radtke said. “Regrettably, that person did not see the text immediately.”

The man Ms Kupfer mentioned is believed to be 31-year-old Shawn Laval Smith, who was identified as the only suspect in her slaying later on Tuesday. He remains at large.

Brianna Kupfer has been described by loved ones as a “kind soul” who “glowed with positivity”.

At the time of her death, the 24-year-old was seeking a graduate degree in architectural design at the University of California Los Angeles (UCLA).

She was also working as a design consultant at the Croft House upscale furniture boutique in Hancock Park in the west of Los Angeles where she was murdered on Thursday 13 January. She leaves behind her parents and three siblings.
