NORTH FORT MYERS, Fla.- Alan Robert Johnson, 33, and Jennifer A. Sparks, 37, were arrested Thursday morning after a lost cell phone containing pornographic images of a child was connected to the pair. Additionally, the child's parents are being investigated for their possible involvment.

A couple found the cell phone in the shopping cart of a Pine Island Walmart on June 2. They contacted police after they looked through the pictures and found images of what appeared to be child pornography. Officers obtained a search warrant for the cell phone and inspection revealed the disturbing nature of the images.

Investigation uncovered that the cellular phone number was issued to Jennifer Sparks. They also found the E-mail address of Alan Robert Johnson in the phone. Detectives connected the E-mail address to Johnson's Facebook account, which was open for public view. Many of the pictures uncovered from the cell phone also appeared on the suspect's personal Facebook page, according to police reports. Additionally, suspect Alan Robert Johnson is a registered sex offender in the state of Florida.

Officers obtained a search warrant for the suspects' home. Within the residence was evidence of Johnson and Sparks producing child pornography images and video, as well as engaging in lewd molestation of a 4-year-old female child. The couple was arrested and transported to the Lee County Jail where they are being held on no bond.

Lee County Sheriff's Office is now investigating the parents of the child. According to LCSO, there is reason to believe that the parents intentionally left the child with Sparks and Johnson. They are looking in to the Tampa couple to see whether or not they were paid by the suspects.

LSCO said that the child stayed with Sparks and Johnson for approximately six weeks before being passed on to someone in Lakeland. They suspect the child's stay in Lakeland served a similar purpose.

The child is now in Polk County with the Florida Department of Child and Families.
