The Putnam County Sheriff's Office and the Florida Department of Children and Families  are assisting Sanford police with the investigation into the safety and well-being of a Sanford family, which includes four children.

They are currently searching for a man and missing child in the case, according to our sister station WKMG in Orlando.

Sanford police said they were notified by DCF to assist with a welfare check on a child living at a house on Oleander Avenue in Sanford just before 8 a.m. Monday.

Police said four children were at the home, according to information provided by DCF. Three of the children were found and placed with foster parents.

At this time, the welfare of the fourth child is still under investigation, police said.

The family had been reunified in November and continued to receive regular visits by case managers, according to a release.

The last reported visit to the home was documented on Feb. 6.

The mother, Rachel Fryer, was at the Sanford Police Department and interviewed by investigators Monday night, according to our sister station WKMG in Orlando.

The Sanford Police Department is asking for the public's help in finding Timothy Gordon, the mother's boyfriend (pictured, above), and Tonya Grooms. Police said they both may have vital information regarding the child's whereabouts.

The Putnam County Sheriff's Office is assisting Sanford Police with a crime scene. Deputies have not confirmed if the missing child had been in Putnam County.

Anyone with information can call Crimeline at 800 423-TIPS (8477). Police said calls made to Crimeline remain anonymous, and tips to Crimeline that lead to solving a felony case are eligible for a cash reward of up to $1,000.
