PORT ST. LUCIE (CBSMiami/AP) — It’s one of those headlines that is difficult to read.

Authorities say a Florida man has been charged with two counts of murder in the killing of an expectant mother and their unborn child.

TC Palm newspapers reported Sunday that 41-year-old Jose Soto Escalera is charged in the death of 23-year-old Tania Wise, whose body was found last month in a ditch. She was about to give birth to their child.

St. Lucie County Sheriff Ken Mascara says investigators have digital forensic evidence and witnesses who confirmed seeing a truck matching Escalera’s near where Wise’s body was found. Authorities have not said how she died.

Mascara says DNA proves Escalera was the father of the unborn child. He is also married to another woman and has four other children.

It wasn’t immediately clear if Escalera has a lawyer to represent him.
