New Orleans, La. - It was nearly a week ago when 1-year-old Londyn Samuels was taken away from her mom,Andrea Samuels and dad Keion Reed.
"It's hard for me right now. I cry but I know crying isn't going to make her come back," says Samuels.
"You could not be upset when you were around her. She wouldn't let you. That smile just warmed my heart," says Reed.
While the pain of their loss will never go away, news of an arrest in the case gives them some hope of justice for what happened.
"It's given us a little peace, but it takes time to recover from something like this," says Reed.
"We are going to keep working very, very hard and we'll continue to do the work that we have in the past to make sure that this stops on the streets of the city," says Mayor Mitch Landrieu.
Mayor Landrieu says this case became a priority for the NOPD.
24-year-old Keelen Armstrong was arrested after police picked him up for speeding on I-10 in New Orleans East.
Police, though, believe there were two shooters on the night Londyn Samuels was killed and her 18-year-old babysitter was shot in the back.
"When the community comes forward and the police are working hard, which they will continue to do, there are serious consequences for activities like this," says Mayor Landrieu.
The parents of little Londyn say they're grateful for the community's support so far, but they're urging more people to come forward.
"If you know something about this, speak up. Stop being scared," says Samuels.
Police want to find a second person, who they say was involved in this shooting.
