Const. Mark David of Longueuil police said investigators searched through the cemetery that borders one side of the bike path and a baseball diamond in Paul Pratt Park. The search began around 9:45 a.m. and wrapped up around 3 p.m.
The 23-year-old Dalcourt died in the early morning hours of Oct. 22, following a brutal attack while walking home late the night before.
A male suspect was arrested by police Oct. 25, but was released the next day due to a lack of evidence.
David said the man remains an important witness.
He asked anyone with information to call 450-463-7211. He said all calls are treated confidentially, 24 hours a day.
