Robert Johnson traded his firefighter turnouts for an orange jail jumpsuit.
The 43-year-old Milwaukee firefighter has been suspended with pay after he was charged with 11 counts of sexually assaulting a 14-year-old girl.
Sources tell 12 News the girl is the daughter of another firefighter.
According to court records Johnson met the girl last year on a website.
Investigators say over the course of six months Johnson had sex with the girl numerous times in his vehicle and at his home on North 45th Street while his three children were also home.
Johnson has been with the Fire Department for 10 years. It's not the first time he's been behind bars.
In 2004 he was charged with one count of sexually assaulting a 14-year-old girl but that case was dismissed.
In this case prosecutors asked for $1 million bail, however the commissioner set it at $200,000.
Johnson was arrested at his home last week.
Neighbors say police removed numerous computers, hard drives and weapons from his duplex.
Police say at some point during this relationship, the 14-year-old girl got pregnant and Johnson told her to have an abortion, however it's unclear what happened.
Neighbors tell 12 News Johnson's three children went to live with their mother in another state.
The fire chief and head of Johnson's union declined to comment.
