In D.C. this year, 105 people were killed in 92 separate incidents, according to Homicide Watch, while the Metropolitan Police Department’s official tally is 103 people.* The majority of the victims were male (94) and black (88), Homicide Watch reports, while 84 shootings — as opposed to stabbings, blunt force trauma and fire — killed people in D.C. The two youngest victims were four-years-old.

In an interview with that website, Metropolitan Police Department Chief Cathy Lanier attributed the rise in homicides to the mass shooting at the Navy Yard. In 2012, the city officially saw 88 homicides, while this year — minus the 12 people who were killed by Aaron Alexis at the Navy Yard — D.C. is on track to close out the year with 91, according to MPD.

“We still have a lot of work to do,” Lanier told Homicide Watch. “Even with 88 murders last year, and that being a landmark year in terms of reductions, it’s still not a happy point for us, we still think that we can get that number much lower.”

*Update: Metropolitan Police Department spokeswoman Gwen Crump says their official tally of homicides this year was 103. The post has been updated to reflect that.

Last year, MPD ruled there were 88 homicides while Homicide Watch said 92. This is why:

It’s worth noting that MPD’s official tally is 88 homicides. That number does not include four deaths that were ruled self-defense. Homicide Watch D.C. counts those cases because the cause of death listed on the case records is homicide and MPD includes those cases in tallying homicide case closures at the end of the year.

This is why the count is different this year:

Two homicides—Marc Griffith and Thomas Terrell Jamison—were ruled “justifiable by citizen” and won’t be included in MPD’s official count.
