(Valparaiso, IN) - Two Valparaiso residents have been arrested on child pornography charges.

Indiana State Police and FBI agents conducted a month-long investigation centered at a residence in the 500 block of Elm Street in Valparaiso. In January, a raid turned up evidence of production of child pornography.

One of the residents, 33-year-old Veronica Solis, was arrested Tuesday. Her four children, ages 7-13, were placed in foster care.

42-year-old Gerald Brann has also been accused. He was arrested at a New Jersey truck stop while out of state for work.

According to State Police, the alleged crimes against children took place while the couple lived in San Antonio, Texas. They will be extradited to Texas and could face additional charges.
