Police in Connecticut are looking for Jennifer Dulos, 50, who was last seen on Friday, May 24, 2019.

Authorities declined to discuss any evidence that they had potentially recovered but said in a statement on Friday that they hadn't recovered a body and that they hadn't arrested anyone.

"We miss her beyond measure — her five young children, her family, her friends, colleagues and neighbors, as well as countless people who have never met her but who have responded to the spirit of grace and kindness that Jennifer embodies," spokesperson Carrie Luft said in a statement Friday on behalf of Dulos' family and friends. "The support and love, the concern for her children and the community efforts to help locate Jennifer have kept us going."

Dulos' disappearance comes amid a custody dispute with her estranged husband, Fotis Dulos. They married in 2004 and filed for divorce in 2017.

The couple has joint custody but the case remains ongoing even with Jennifer Dulos missing.

According to a Tuesday letter from Fotis Dulos' attorney, when Jennifer Dulos was reported missing, her nanny brought the couple's five children to Jennifer Dulos' mother's home, where an armed bodyguard was hired to watch them.

Friday's statement from Jennifer Dulos' family and friends did not specify where her children were, but said, "Please be assured that Jennifer’s five children are safe and well-cared for. "

In a message to the missing mother, the statement said, "Jennifer, we love you and we miss you, and we remain hopeful that you will return to us safe and sound."
