Police said the person of interest had a “previous relationship with Ms. Murphy” but is not Jaclyn’s father. Three were last seen together on Monday at a suburban shopping mall.

Murphy was found dead around 10:20 p.m. Tuesday, when officers conducted a well-being check at her home in Wheeling, after receiving a missing person report, because she hadn’t shown up to work or contacted her family since Monday.

When officers arrived at the home, they found the door unlocked, and Murphy dead inside. Jaclyn was missing and has yet to be found.
