Police continued the search for the 43-year-old mother Sylvia Schulze and 12-year-old daughter Miriam on Wednesday by a lake and forest in Harburg near their family home in Lower Saxony.
The body of father Marco Schulze, 41, was discovered drowned on July 31st in the Elbe River.
Investigators said there was no evidence of foul play on his body and that they are considering the possibility of suicide.
The whole family has been missing since last month when acquaintances reported to police that they couldn't get in contact with them.
The father was last seen on July 23rd, when witnesses said they saw him driving his wife's car. The car was found parked at the family home, though, when police began their search.
A witness told police that she had seen the family all together at the lake where the police have now been searching.
Police said they believe the witness saw the family on July 22nd, the last school day before summer vacation for Lower Saxony.
Police said they have around 60 people searching for the mother and daughter.
