UPDATE (June 27, 2018 2:08 p.m.):

Video surveillance was recovered that implicated McGuire in Cindy Testerman's death, leading detectives across the street to the home of the second victim, with whom McGuire had been staying recently.

Judy Elizabeth Slebzak (66) of the 7900 block of Roseland Avenue, 21237, McGuire's step-mother, was discovered hidden in a cedar chest in her home during the search following McGuire's arrest. McGuire admitted his involvement in both women's deaths during a post-Miranda interview.

Police now believe that McGuire may have murdered Judy Slebzak up to a few weeks ago, then used her vehicle for transportation while selling some of her possessions to obtain money for illicit narcotics. When Cindy Testerman began questioning him about her whereabouts, police believe he responded to her home on Saturday, June 23, and murdered her, as well. He took possessions from her home, including her vehicle, and sold them for money to purchase additional narcotics.

McGuire is currently held without bail at the Baltimore County Detention Center pending a bail review hearing.
