John James “Jack” Gilligan of Nutley, formerly of Montclair, a retired 25-year member of the Montclair police force, died after a lengthy illness on Sept. 27, 2021, at Hackensack University Medical Center. He was 70.

Mr. Gilligan was born during a hurricane in November 1950 to Thomas J. Gilligan Sr. and Mary Agnes (Giblin) Gilligan.  

He proudly served for 25 years in the Montclair Police Department. He would often tell stories from his days on the force that enthralled and amazed family and friends, or made them laugh. He retired from the force in 2000. 

Mr. Gilligan also served in the New Jersey National Guard. 

SAVE MONTCLAIR LOCAL: We need your support, and we need it today. The journalism you value from Montclair Local, a 501(c)(3) nonprofit organization, depends on the community's support — we exist because the old model of selling ads alone just can't fund journalism at the level we endeavor to provide. That's why you've seen other local newsrooms cut back staff or shut down entirely. Montclair Local was created because we believe that's unacceptable; the community's at its best when triumphs are celebrated, when power is held to account, when diverse lived experiences are shared — when the community is well-informed.

Montclair is seeking to raise $230,000 from donors, members and grantors between Oct. 1 and Dec. 31 to put us on firm footing for 2022, and continue supporting the hard work of our journalists into the new year and beyond.

In his early years he worked at Frank & Rick’s gas station and Cohen Confectionery, and was a long-haul moving man for United Van Lines, all of Montclair.

After retiring, Mr. Gilligan was a successful day trader.

He enjoyed spending many hours with his neighbors and their dogs. He would play with, dog-sit and train those pets and sneak them treats when he thought no one was looking (but everyone knew he was doing it).

Mr. Gilligan is survived by his wife, Marsha (Rosa), of Nutley; his brothers, Tom (Mary Jane), of Spring Lake, Ed, of Bayonne, and Jim (Ana), of West Milford; extended family, George and Leslie Metzger and Donna Rosa, and many nieces and nephews. In addition, he leaves behind his current canine companion, Thelma. His longtime canine companion Samantha crossed the rainbow bridge a few years ago. 

He was predeceased by parents, his brothers, Mark (surviving spouse, Betty) and Bob (surviving spouse, Ellen), and nephews Sean and Danny. 

Visitation is at the Hugh M. Moriarty Funeral Home, 76 Park St., on Friday, Oct. 1, from 3 to 8 p.m. There will be a Mass of Christian Burial at Church of the Immaculate Conception, Montclair, on Saturday, Oct. 2, at 10:30 a.m., followed by entombment at Glendale Cemetery, Bloomfield.
