Holly Richardson cold case remains unsolved, one year after 34-year-old mother's killing

WEST PALM BEACH, Fla. - A family is still searching for answers a year after 34-year-old Holly Richardson was found shot and killed a block from her home.

Robyn Richardson clutches a photo album in her hands.  The book is covered in butterflies, filled with photos of her daughter Holly.  Holly's beaming smile shines under reflective aviator-style sunglasses in several photos.  In others, she is puckering her lips like a kiss, dancing on a beach.  Other photos show Holly embracing her daughter, a spitting image in Holly's vibrant presence.

Holly was found shot to death in her car October 23, 2014.  She was a block from Good Samaritan Medical Center, a block from where she was last seen on security footage at a convenience store, and a block from her home.  It was just off Palm Beach Lakes Boulevard and Madeira Court near Dixie Highway.

In the year since Holly's death, Robyn says she has been devastated.  The West Palm Beach Police Department continues to search for new clues in the case, hopeful there will be a new development.

"She was my youngest," Robyn said, as she started to cry.

West Palm Beach Police investigators believe there are witnesses to the murder who have not come forward.  Holly was seen on a surveillance camera in a gas station just minutes before she was killed.  Investigators say, even on a silent black and white tape with grainy footage, Holly's vibrancy showed through.

Robyn wants answers for Holly's large group of family and friends, especially for Holly's now 9-year-old daughter.

"[Holly's daughter] says, the bad guy will get punished.  She doesn't know a whole bunch, but she knows, enough," Robyn said.

Anyone with information about the case should call Palm Beach County Crime Stoppers at 1-800-458-TIPS or text 274637 and include the letters WPBPD in the body of the text message. You can remain anonymous. You can also reach West Palm Beach Police at 561-822-1666.
