The highest-ranking remaining member of the Mayor's Office on Criminal Justice has submitted her resignation, officials confirmed Tuesday.
Shannon Cosgrove, deputy director of the office, will be the fourth member of Mayor Stephanie Rawlings-Blake's criminal justice team to leave in recent weeks.
Three others have left the office as Baltimore endures a rash of homicides and other violence following last month's rioting and unrest.
Attempts to reach Cosgrove for comment were unsuccessful Tuesday. A spokesman for Rawlings-Blake could not immediately say when Cosgrove's last day would be.
Cosgrove was hired in February 2014 at an annual salary of $81,600.
Angela Johnese, director of the criminal justice office, and Heather Brantner, the mayor's Sexual Assault Response Team coordinator, left their city posts Friday. Officials declined to say under what terms they departed.
LeVar Michael, who led the city's anti-violence program Operation Ceasefire, left his position voluntarily a few weeks ago.
The City Council is expected to discuss the turnover and the mayor's strategy for addressing the surge in violence at a budget hearing Wednesday. This month has become the city's deadliest since 1999, with at least 35 people killed. More than 100 people have been killed in Baltimore this year.
