Pinellas Park Police Detectives are investigating 8 unsolved hit and run fatality cases.
The number of deaths has more than doubled in the city and the number of hit and run crashes has increased by almost 33 percent.
Catherine Mantini-Sease lost her son, Andrew Mitchell, on April 17. He was killed trying to cross 66th street.
"I can't tell you what this has been like for me….I mean….my own child," Mantini-Sease said.
Mantini-Sease spoke with ABC Action News from her home in Delaware. Her son moved to Florida 3 years ago. He lived in West Palm Beach and was visiting Pinellas Park that night.
Authorities said Mitchell walked in front of a Sunfire. He was thrown and then a dark SUV ran over him. The driver of the Sunfire stopped, but the driver of the SUV did not. Authorities are looking for the driver of the SUV.
"I think for all of us, you know, we just want to know what happened. Who did this? It's been really hard," Katelyn Beird, his sister, said.
They hope someone will come forward soon. Mantini-Sease remembered the words her son said to her 2 days before this happened.
"Our last words to each other were I love you because that was something that he always said to me. I love you mom," Mantini-Sease said.
Mitchell's family said they will remember his personality, how much he loved the outdoors and playing with his siblings.
"He was a really great person. He would always be the first one to make us or anyone else laugh. He was goofy. I think that's helped me and my brothers remember him," Beird said.
If anyone has any information about this case, contact the Pinellas Park Police Department immediately.
