45 murders in 31 days
July saw 45 homicides across Baltimore, a toll that matched the deadliest month in the city’s modern history and came amid a violent crime surge that has stretched the entire summer. The killings occurred across the city, overwhelmingly in historically impoverished neighborhoods. The victims included a 5-month-old boy and a 53-year-old grandmother, a teen stabbed to death in a dispute over a cell phone and a carryout deliveryman killed in a robbery.

Dublin is a bit less than twice the size of Baltimore. That would work out at approaching 90 murders in a month.
