The boyfriend of Korryn Gaines will appear in court Wednesday morning for a preliminary hearing.
Kareem Courtney faces drug and gun charges.
The 39-year-old was staying with Gaines at her apartment when Baltimore County police arrived on Aug. 1 to serve arrest warrants.
Gaines barricaded herself inside her apartment with a 5-year-old boy and pointed a shotgun at officers. She was shot and killed by Officer First Class Ruby.
Courtney and Gaines' mother are suing Baltimore County and Ruby for $2 million.
