"Suddenly, I hear a tremendous noise, like when somebody hits another car, and I run to the window and I see a cane," said the victim's daughter Monica Gutierrez.
Gutierrez said she ran outside and found his body lying in the street.
"At least they should stop and give some help. My dad is not an animal, even an animal, you can just help," Gutierrez said.
Witnesses reported seeing a black car fleeing from the scene, but police have no other leads. Lt. Tom McNeal of the L.A. County Sheriff's Department said they have no description of the driver and need the public's help.
Barragan had spent his career as a horse trainer, and he was a father of 12.
"He's a father, he's a grandfather, he's got kids, he's got friends, he's a person. You just don't leave somebody laying in the middle of the street," said Maria Solia, a friend of the victim.
On Thursday, family placed candles at the spot where their father was killed, less than a year after they lost their mother to illness.
"Please help turn yourself in to clear this up because it's not fair. My heart is broke," pleaded the victim's son, Gabriel Barragan Jr.
Anyone with information is urged to call the L.A. County Sheriff's Department at (877) TIP-LASD.
