A 43-year-old Japan Coast Guard member has been found dead in what is believed to be a suicide after apparently killing his 9-year-old daughter Friday in Aichi Prefecture, police said Saturday.

The police received an emergency call at around 9:55 p.m. the same day from a 13-year-old boy who said his father had killed his younger sister.

The girl, 9-year-old Mizuki Kanda, was confirmed dead after she was taken to a hospital from their home in the city of Tokoname.

The siblings' 41-year-old mother told the police that she found her daughter lying in a room when she got home around 8 p.m.

She said her husband told her he wanted her to die with him and attacked her with a kitchen knife, police said.

The father, who worked as helicopter maintenance engineer, also tried to attack the son when he came home, but his mother protected him.

Marks indicating strangulation were found on the neck of the girl, who was a third-grader, police said.

The father's body was later found in the bicycle parking lot of an apartment building some 2 km from their house, apparently having jumped to his death, according to the police. No suicide note was found.

The woman told police her husband was having money problems.
