TENAFLY, N.J. (NorthJersey.com)  -- The bodies of three people found inside a home this week were so badly decomposed that their identities will have to be confirmed via dental records, the Bergen County Prosecutor's Office said Saturday night.

Authorities had hoped to have a relative identify the bodies discovered Friday night in the Tenafly home, but those plans were scrapped Saturday due to the condition of the bodies, said Frank Puccio, the executive assistant county prosecutor.

Puccio said officials would likely not be able to confirm the victims identities until sometime next week, but added that authorities believe the three, an elderly male, an elderly female and a younger male, were the people who lived in the home.

Each victim had sustained multiple stab wounds, and authorities said the bodies could have been in the home for as long as a week.

Meanwhile, authorities continued to search for clues and a motive in the deaths.

Neighbors said investigators searched the entire block, including sewers, for clues late Friday and Saturday, but it was not known what, if any, evidence was recovered.

Authorities said the house had not been ransacked and there were no signs of a struggle.
