Prayers are to be said in church for the family of a police inspector who killed his wife and daughter in a frenzied attack at their home just days after he was sacked.
Reverend Canon Lee Francis-Dehqani, from Oakham Parish Church, in Oakham, said he will lead prayers for Tobias and Samantha Day and their children during the Sunday service.
Mr Day, known as Toby and once described by police chiefs as "never off duty", is thought to have killed his primary school teacher wife Samantha and youngest daughter Genevieve, six, and attacked Kimberley, 15 and Adam, 13, before taking his own life on Thursday at their home in Melton Mowbray, Leicestershire.
The surviving children remained in a "stable" condition, a hospital spokesman said.
Rev Canon Francis-Dehqani said he had known the family for seven years, since he was appointed at the church in 2004.
"They were a lovely family and regular worshippers at the church. Prayers will be said for the family and for those who died during our service tomorrow."
Police have launched a murder inquiry and results of post-mortem tests are expected later.
Rev Canon Francis-Dehqani said he was working with the family and police liaison officers on the funeral arrangements.
The attack in the semi-detached family home is believed to have been fuelled by Mr Day's dismissal last Thursday from Leicestershire Police for misusing force computers.
The force declined to comment on reports that Mr Day suspected his wife was having an affair and had used the police computer system to search for information.
