On Wednesday morning, at police headquarters in Doral, detectives and the teen’s mom asked for help.

“He was my baby,” Lliliam Alonso said while holding back tears.

Sanchez Alonso was shot the day before Mother’s Day on Saturday, May 9th of 2020, at around 4 p.m., in the area of Southwest 179th Street and 105th Avenue.

The teen’s mom said he told her he was going out fishing with friends. Then she got a call her son was in the hospital where he died.

“It’s hard to get up, it’s hard to eat, it’s hard to think… It’s hard to do it all,” she said.
