The San Francisco Chronicle reported that Childs allegedly had a dispute with his boss that led him to hack the system.
According to the Chronicle, Childs was ordered to leave work July 9 for alleged insubordination. While in jail, he remains on the city payroll, reportedly earning $127,735 a year.
Childs was convicted of aggravated robbery and burglary in 1982, the Chronicle also reported.
Last week, Jacobs called his former client's $5 million bail "ridiculous and uncalled for."
"Murderers get $1 million bail and this guy didn't kill anyone. It doesn't make any sense," he said.
Derryck defended the high bail and said Childs' alleged actions constituted a "threat to public safety, and that bail was appropriate."
Despite Jacobs's defense of Childs in the media, the public defender's boss told ABCNews.com that its office would stop defending the network technician.
"Our office is declaring a conflict of interest. At the hearing, the court will appoint a private attorney," said Teresa Caffese, the chief attorney for the San Francisco Public Defender.
"We're part of the city and county of San Francisco, and we believe there may be a conflict," she said.
According to media reports, Childs' new attorney, Erin Crane, arranged the meeting between her client and the mayor.
