After the attack on US pop star Lady Gaga's dog sitter in early 2021, a second perpetrator was sentenced to several years in prison.
A Los Angeles court on Thursday sentenced 28-year-old Lafayette Shon Whaley to six years in prison for robbery.
A week ago, a four-year prison sentence had already been imposed on a 20-year-old accomplice.
Three men attacked Lady Gaga's dog handler Ryan Fischer in February 2021 in an attempt to snatch the singer's three French bulldogs.
One of the perpetrators shot Fischer down and seriously injured him.
The attackers were able to escape with two of the bulldogs - Koji and Gustav, the third dog - Miss Asia - escaped the robbers.
The police do not believe that the perpetrators originally knew who owned the dogs.
French bulldogs are very valuable even without famous owners: dogs of the sought-after breeds are sold for thousands of dollars.
Lady Gaga later got her pets back after offering a half-million dollar reward.
A woman turned the dogs over to police and said she found them leashed to a post.
The alleged finder was also arrested - she is said to be an accomplice of the perpetrators.
The alleged shooter was released from custody last April because of an administrative error, as the police had to admit in July.
He was arrested again last week.
His charges include attempted murder, robbery, conspiracy to commit robbery and assault with a semi-automatic weapon.
