An investigation is underway after a teenager was found shot in the hand in Southwest Miami-Dade on Saturday night, deputies said.

Around 8:04 p.m., Miami-Dade Sheriff's deputies responded to the area of 11345 SW 191 Ln regarding a "shooting involving a juvenile" near South Miami Heights.

MDSO said that the teen was walking north toward a restaurant when he was shot in the hand. He then ran to seek help, and that's when a good Samaritan stepped in and kept him safe until deputies and paramedics arrived.

At the scene, numerous spent bullet casings were found by deputies when they arrived on the scene. At this time, no suspects are in custody, MDSO said.

Witnesses told CBS News Miami that they were very disappointed that this happened on a Saturday night, as children were playing outside.

"We heard gunshots. We thought they were fireworks because we usually hear a lot of fireworks around the area, but then we noticed it was gunshots," said witness Yunir Diaz. "[We] immediately went to go get the kids and brought them inside. It stopped for a while but then it continued again. There were between 20 and 30 shots."

Community activist Darrel Collins told CBS News Miami that the community was "very scared" and solving the issue of gun violence in the area has been an "ongoing process."

"I have never seen the commissioner or anyone over there condone the parents or nothing, but something needs to be done," he said.

MDSO is asking for the community to help with finding the shooter. Anyone with any information is asked to call Miami-Dade Crime Stoppers at (305) 471-TIPS (8477).
