Police are investigating a murder-suicide at a family home in the wealthy town of Laren, where a former senior ABN Amro banker, his wife and daughter have been found dead.

Jan Peter Schmittmann, 57, was head of ABN Amro Nederland and left the bank with €8m in compensation when it was nationalised in 2008.

The body of Schmittmann, his 57-year-old wife and 22-year-old handicapped daughter were found at their large detached home in Laren on Saturday. Another daughter was not at home at the time.

‘We have received a lot of additional information since Saturday and that needs looking into,’ a police woman told reporters.

The cause of death and more information about what happened in the house will take several days to establish, she said.
