The ambush shooting of NYPD Officer Miosotis Familia, 48, who was sitting in one of the RV-like mobile command centers, has added to the urgency of protecting the vehicles.
Crews from the NYPD's buildings-maintenance division spent Sunday freshening up the exterior of the The World Changers Church on Grand Concourse, where Familia will be waked.
A New York Police Department officer died after being shot in the head early Wednesday morning, according to news outlets in New York City.
Hundreds gathered Saturday night for a vigil to remember Familia, and flower bouquets line the sidewalk outside Familia's 46th Precinct stationhouse.
On Friday, Familia's oldest daughter, Genesis Villella, 20, released a statement, "She was incredibly amusing".
Familia - a 12-year veteran and mother of three - was gunned down in cold blood by cop-hater Alexander Bonds just a few blocks away as she sat in an NYPD vehicle around 12:30 a.m. Wednesday.
The funeral service will be held Tuesday at 10 a.m.at the same church. She was [an] especially warm and erudite woman who fiercely loved her children and went to work every day proud to do her job, to protect us. Viewing will take place from 2 p.m.to 4 p.m. and from 7 p.m.to 9 p.m.
"She was an exceptional person, and I know she's up there with God and with us", she said.
