One of the two shooters who authorities say gunned down a Jersey City police officer and three civilians - two of whom were Orthodox Jews - wrote a note that read “I do this because my creator makes me do this and I hate who he hates,” according to a report on NYPost.com.

Investigators found the handwritten note inside the van left outside the kosher market by attackers David Anderson, 47, and Francine Graham, 50, the Post reported, citing law enforcement sources. The note was scrawled by Anderson, the report said.

There is evidence the shooters “expressed interest" in certain hate groups such as the Black Hebrew Israelites - but authorities believe they acted alone, not as part of any organization, New Jersey Attorney General Gurbir Grewal said at a news conference Thursday. He declined to address any notes found in the van.

Anderson and Graham shot and killed Jersey City Det. Joseph Seals at a cemetery before driving to the market, where the walked in with guns drawn and killed three people - Moshe Deutsch, 24, a Hasidic man who was visiting from Brooklyn; Leah Minda Ferencz, 33, a co-owner the Kosher grocery with her husband, who was not present at the time; and Miguel Douglas Rodriguez, 49, of Jersey City, who worked in the store.

Anderson and Graham were killed following an exchange of gunfire with police that lasted more than three hours.

A wake for Seals will be held Monday with a funeral mass to follow Tuesday in Jersey City.

Funerals for Deutsch and Ferencz were held Wednesday in Brooklyn, New York.
