When Castellano arrived at the station, the watch commander was already waiting for him. Word had spread fast; Whitmore had called ahead. Castellano was immediately placed on administrative leave pending investigation. His badge and gun were taken, and he was sent home with instructions not to discuss the case with anyone.
The investigation began that same day. Internal Affairs assigned two senior investigators. They reviewed Castellano's body camera footage first. The video was damning: you could hear Castellano's exact words: "We got a call about someone who didn't look like they belonged here." You could hear Whitmore calmly explaining that he lived there and was washing his car in his own driveway. You could hear Castellano telling him to just cooperate without any legal justification. The audio captured Whitmore's controlled anger when he asked, "You're really going to do this?" And it captured the moment everything changed—when Whitmore identified himself as Sergeant Darnell Whitmore and told Castellano he was in big trouble.
They pulled Castellano's personnel file and found the nine previous complaints. Now they had context: this wasn't an isolated incident; this was a pattern that had been ignored.
They interviewed Whitmore in detail. Whitmore provided a thorough statement. He explained that he had experienced profiling before as a civilian, but experiencing it from one of his own officers while off duty was particularly disturbing. He said it raised serious questions about Castellano's judgment and whether he had been engaging in racial profiling throughout his career.
The investigators interviewed Castellano three days after the incident. Castellano tried to defend his actions. He said he was responding to a legitimate call. When investigators pointed out that the call gave no specific location and no description beyond "Black male," Castellano said he had to make a judgment call.
Investigators asked why he assumed Whitmore was the person from the call when Whitmore was clearly washing a car in a residential driveway. Castellano said the caller reported someone who didn't look like they belonged. When pressed on what that actually meant, Castellano couldn't articulate anything that didn't come down to race.
They asked Castellano what he meant when he told Whitmore to just cooperate. Castellano said he was trying to de-escalate. Investigators pointed out that demanding ID without legal justification isn't de-escalation—it's escalation, it's a violation of rights.
They asked Castellano if he had known Whitmore was a sergeant when he approached. Castellano said no. They asked if that would have changed his approach. Castellano said probably.
That answer was revealing. It meant Castellano would have treated a white homeowner differently than he treated Whitmore. It meant his approach was based on assumptions about who belonged in the neighborhood, not on actual suspicious behavior.
The investigators reviewed the original call to dispatch. The anonymous caller had simply said there was a Black male on Maple Street who didn't look like he belonged and was acting suspicious around cars. The caller didn't give a specific address, didn't describe any criminal behavior, didn't provide any details beyond race, a vague location, and the loaded phrase "didn't look like he belonged."
