Today’s death is the 73rd murder in Dallas so far this year. Dallas police Lt. Chuck Young, with the Crimes Against Persons Division Special Investigations/Cold Case, said many of the cases have been solved but that there are about 20 unsolved cases that investigators have no leads on and have essentially gone cold.

The number of homicides this year is up more than 7-percent from last year. From January 1 until June 3, 2016 there were 66 murders in Dallas and there were 171 murders in all of 2016. Young said that at the rate it’s going the city is on pace to match that number this year.
