NEW ORLEANS -- There's a growing number of murders in the city that remain unsolved.

A recent triple shooting in New Orleans East is among them. That incident comes just a week after a mother and her two young sons were killed in Gentilly.

No one has been arrested in either case.

Numbers show a drastic drop in murder clearance rates over the past few years. For the families affected by the violence, not having anyone in custody for the death of their loved one is torture.

For Michele Jackson, sifting through old ID cards of her son's belongings makes her feel closer to him.

"I'm just waiting for him to walk through that door," Jackson said.

Jackson's son, 34-year-old Walter Jackson, was shot multiple times and killed January 4, 2015.

"My daughter had to ID the body," Jackson said. "My daughter, not his mother! My daughter, cause they didn't want his mother to see him," Jackson said.

To this day, no one has been arrested or charged. Jackson is not alone.

"I met one lady one day and she told me her son had been dead 10 years, and they still haven't solved her son's murder," Jackson said.

WWL-TV crime analyst Jeff Asher constructed a chart from homicide spreadsheets, dating back from 2010 to 2016.

In 2010, the numbers stood at 54.1 percent. In 2015, it was only 26.3 percent. Asher also noticed a correlation between less manpower and the clearance rate numbers.

"The police can't do it all by themselves," Jackson said. "They need the community's help. They need the public's help."

Community involvement in solving cases is something needed in every jurisdiction. Jefferson Parish Sheriff Newell Normand touched on the topic this week following a quadruple murder arrest in Metairie.

"If we took the mindset that we're only willing to accept on our street what we're willing to accept in our home...we would take back every street, block by block in Jefferson Parish and throughout the metropolitan area. If we had that simple approach," Sheriff Normand said.

Even though it's been two very painful years, Jackson still holds onto faith that someone will turn themselves in.

"One day I will see him again," Jackson said. "We will be together one day. But before that day comes, I'm gonna make sure that they catch the person that did this to him."

WWL-TV reached out to NOPD about murder clearance rates. We are waiting to hear back.

Crime Analyst Jeff Asher also found the number of detectives investigating murders is down. In 2013, the NOPD had 41 sworn officers in the homicide division. As of March 2017, they only have 29. Click here to see the study.
