The satellite booms of television news trucks stood high above the one-story Queens church where family, friends and National Guard members gathered on a crisp Friday morning for the funeral service of Noel Polanco, the unarmed 22-year-old man killed by the New York police last week.

Inside, many who packed the small, windowless church in Corona wore uniforms, both official and more personal, that reflected the diverse passions pursued by Mr. Polanco.

There were the men and women in military dress, a testament, friends said, to the pride he felt in his four years of service in the Guard. There were others, in the matching black leather vests of a local car club, who spoke of how Mr. Polanco tinkered with an old Honda before saving enough money working at a dealership to buy a new one. Several friends wore T-shirts with his likeness, or sweatshirts with his nickname and a somber message: “R.I.P. Sparxxz.”

Mr. Polanco drew tattoos and loved music; he avoided trouble and aspired to join the Police Department. He worked hard at several jobs, friends and family said, and still jumped at the chance to do favors for those in need.
