The Los Angeles Police Department identified the suspect as 39-year-old Jonathan Madden. He was arrested Monday at his home in South Los Angeles.
He is charged with murder and two counts of attempted murder, according to court documents. He is being held on $2 million bail.
Investigators believe Madden shot Alejandro Garcia, 41, while in a drive-thru around 11 p.m. at the food chain’s Avalon Boulevard location. He reportedly refused to take a counterfeit $20 bill and was working the night shift with his 19-year-old son.
During a Tuesday night vigil, family members said Garcia was a father of three who worked at the Taco Bell one night per week to earn extra money, KTLA-TV reported.
“I hope that one day I’m just like him. He put our family first for everything,” he said. “He [suspect] had to take someone that I really loved and I considered my best friend. He wasn’t just a father. He was my best friend too.”
LAPD Chief Michel Moore attended the vigil and announced an arrest had been made but did not name a suspect.
