LOUISVILLE, Ky. (WDRB) -- They're hitting neighborhoods looking for criminals and guns, trying to put a dent in all the violence.  

"Let me see your hands! Put your hands on top of the car," says Sgt. Rob King with the 9th Mobile Division. He says, "It's a real life game of cat and mouse."

Officers of the 9th Mobile Division, all in unmarked cars, never know what they'll find when they hit the streets each night.

"A lot of these girls are prostitutes," said King. "The ones you see hanging around here."

WDRB went undercover with Sgt. Rob King and Detective Billy Cundiff overnight. From carjackings to assisting the ATF to murders and shootings, 9th Mobile is responding to violent crimes.

Lt. William Hibbs with the 9th Mobile Divsion says every week he gets updated maps showing the hot spots.

"Our primary areas of focus are the 1st Division, 2nd Division, and 4th Division," Hibbs said. "We do venture into the 6th, the Newburg division "

"Right now, we've had an influx of activity south of Broadway near Greenwood Avenue anywhere between 45 and 48th Street. Tips from places like the Portland and Russell neighborhoods lead police to hit those areas as well as Smoketown, Shelby Park and Newburg. Here, police were watching a car.
Then another car pulls up next to us and a second car in front of us.

"Are you serious? Are you freaking kidding me?" King said. "I don't know. I'll hit my light, you grab him and I'll grab him. You grab that car. I'll grab him."

Out of the five people, four were arrested. Some had outstanding warrants and police also found marijuana. The men were taken to Metro Corrections and then it was off to the next location.

9th Mobile started as a group called "Operation Trust" when the VIPER unit was dismantled. Since February of 2015, it has taken 749 guns off the streets. 

Police say people are selling guns for $150 and $200. 9th Mobile say 16 percent of guns confiscated are stolen; 275 came from convicted felons and 44 from juveniles. 

We found a group of kids hanging around a gas station around midnight, no sign of their parents.

King says to a kid, "Why are you out so late?" He says, "I came from soccer practice. They said they were going to pick me up." King says, "What time was soccer practice?" The kid says, "Soccer practice was over about 8." King responded, "What have you done for the past four hours?"

Just after midnight, on another traffic stop, police found even more drugs. They show us the marijuana that was confiscated. King says, "It's probably 4 ounces, [he] probably just bought it. Smells pretty good too, pretty good quality."

Police say the two men had $1,800 in cash.

"We'll stop guys out here that have got $4,000 and $5,000 cash on them," Cundiff said. "I ask them where do you work?" He says they respond, "I don't have a job."

9th Mobile and Operation Trust have confiscated a lot of drugs while looking for guns. More than 7,500 pills and 163 pounds of marijuana.

Police are now heading to the Park Hill housing project looking for a car jacking suspect. The LMPD helicopter is up searching too. Officers are setting up a perimeter all around the complex. The stolen car hit a pole, the doors are open and the two people inside took off running. The gun was ditched in the bushes along with a black t-shirt. No sign of the men and it makes it difficult once they run into a housing complex.

But police think they'll eventually be found along with other criminals.

"We take great pride that we are interacting with the worst of the worst," Hibbs said. "I've got three binders of those individuals. We track... we know ... we study those individuals and their associates."

Hibb says the goal is "to keep people alive every single night." For King and Cundiff. that's their goal too.

"We're on the streets," King said. "We're not as visible, but we still have the community's best interest in mind."
