The department will also impose a moratorium on serving warrants until they're certain each has been thoroughly vetted, police Chief Hank Stawinski said.

WASHINGTON — Wednesday night’s officer-involved shooting in Prince George’s County, Maryland, occurred when a warrant was served at the wrong home, police Chief Hank Stawinski said Thursday.

When a team of officers burst into a District Heights apartment around 10 p.m. to serve the warrant, they didn’t find the suspected drug dealer they had been trying to arrest.

Instead, they found a father and his daughter.

“We believed that we were serving a search warrant at that [suspected dealer’s] address.The investigation had led us to the wrong address. It led us to the address of a responsible hard-working citizen.”

When police arrived at the residence, located in the 2700 block of Lorring Drive, they knocked and announced themselves, Stawinski said, but the father didn’t hear them. (When asked why the father didn’t hear them, the chief suspected it was because he had fallen asleep while watching television.)

Amid their entrance, the chief said, the father armed himself and fired one shotgun blast, wounding two officers. An officer fired one shot in return, but “it did not take effect.” The officer who discharged his weapon has been identified in a news release as Cpl. Daniel Siculietano. No one was struck by his weapon, and he has been placed on administrative leave pending the outcome of an investigation, which is standard procedure.

Realizing they were police, Stawinski said, the father then dropped his weapon and told them not to shoot his daughter, whom he had told to go to the back of the apartment.

One officer has been treated and released, Stawinski said Thursday. The other required surgery on his arm.

The father, Stawinski said, was taken into custody and questioned, along with his daughter.

“This man was devastated when he realized that he had fired upon police officers,” he told reporters. “He was as worried about their safety once he realized that had happened as he was worried about the safety of his own daughter.”

The father will not be charged with a crime.

A confidential informant had led police to the father’s address, the chief said. “Our officers had worked to corroborate the information from that confidential informant. However, we did not draw the right conclusion.”

As a result, he said, the department will impose a moratorium on serving warrants until they’re certain each has been thoroughly vetted. Stawinski expects that moratorium to last roughly 24–48 hours and impact a “handful” of warrants.

Stawinski wouldn’t rule out disciplinary action or structural changes in the department.

“I’m not going to put another father like myself in that position,” Stawinski said. “I refuse to.”

During a news conference early Thursday morning following the incident, police media relations director Jennifer Donelan told reporters, “The relief that we are feeling right now is really hard to put into words.”
