Thijs H., the man suspected of fatally stabbing three people while they were walking their dogs in The Hague and Heerlen, is or was being treated by the Mondriaan psychiatric institution in Maastricht, a spokesperson for the Public Prosecutor said on Thursday. The 27-year-old man from The Hague will be arraigned next week, the Prosecutor said.

The Mondriaan clinic refused to comment on the matter, due to the ongoing police investigation, reports. H.'s lawyer Serge Weening also did not want to say anything, because his client is in restricted custody. This means that H. is only allowed contact with his lawyer, and the police and lawyer can't reveal details about the case. 

The 27-year-old man from The Hague was arrested on Wednesday evening in South Limburg, after a national search was launched for him a few hours earlier. H. is suspected of stabbing three people to death.

The first victim, a 56-year-old Japanese woman, was found dead on Galgenpad in the Scheveningen woods on Saturday. She left her home on Nicolaistraat in The Hague to go walk her dogs on Saturday afternoon. Passersby found her body an hour later, with her cargo bike and disabled dog. Her other dog was found a time later.

A 68-year-old man and a 63-year-old woman were found killed in nature reserve Brunssummerheide near Heerlen on Tuesday. A passerby found the woman's body first and called the police. The man's body was found about a hundred meters away. Like the Hague victim, these two victims were also with their dogs. 

Former students of Leiden University, who studied in the same faculty as H. in the 2014/2015 academic year, describe him as soft-natured and friendly, if a bit of a wallflower.
