Police said Caprio would have marked four years with the Baltimore County Police Department in July.
"The community I represent stands united in grief for this fallen police officer, and our hope is that all those involved are brought to justice", Marks said.
Speaking on radio station 105.7 The Fan, Caprio's husband Tim Caprio said, "I'm just still grieving". He said he had no information about whether she had fired her own weapon.
Three other suspects - all teenage boys - were also taken into custody in connection with the Monday killing of officer Amy Caprio, police said.
The black Jeep was later found abandoned in nearby Nottingham near where Harris was later arrested. The boy is being charged as an adult, according to court documents, and is being held without bail. Since Baltimore County Police have not confirmed that the officer was shot, the tweet was removed.
Witnesses described seeing Caprio with her gun drawn and marching towards the Jeep on Monday afternoon.
Investigators will review body camera footage to determine what happened, Sheridan said. She was transported to Franklin Square Hospital, where she was pronounced dead, the probable cause documents said.
Bickel detailed Harris' numerous recent run-ins with the law, including a series of auto theft arrests and a history of running away from juvenile facilities.
The records say he told the detective he drove the vehicle at the officer.
Witnesses reported hearing a pop before seeing a Jeep run over the officer in the suburban community of Perry Hall, Maryland.
The department initially said it planned to release his name and charges after the hearing, but soon after identified him as Dawnta Anthony Harris, of West Baltimore. He has been charged with first-degree murder.
Authorities also say three additional teenagers have been taken into custody after a female officer was killed. Police Chief Terrence B. Sheridan said the officer was responding to a call for a possible burglary involving four suspects.
"Harris admitted that he had been waiting in the driver's seat of the Jeep Wrangler as other associates were in the process of committing a burglary", the charging document states. Caprio followed him, got out of her vehicle and demanded he exit the Jeep, he said, according to court documents.
Scott Shellenberger, the state's attorney for Baltimore County, told The Associated Press the teen has been charged as an adult.
Caprio, whose relatives could not immediately be reached by The Associated Press, won an "Officer of the Month" award for the Parkville precinct in December.
The killing of a Baltimore County police officer on May 21 kicked off a massive lockdown and search for the suspects after police were investigating a call for a suspicious vehicle.
"Our prayers go out to this fearless officer's family, @BACOPoliceFire, and the Baltimore County community", Maryland Gov. Larry Hogan (R) said in a tweet Monday. Officers were searching the area Monday night for suspects "who we believe are armed and unsafe", Police Chief Terrence Sheridan noted earlier.
What exactly unfolded in the seconds afterwards remains unclear but witnesses said they heard her shouting 'Get out of the car!' several times and then a gunshot. He said he left the Jeep where officers later found it.
One of the Kureks' other sons - a volunteer firefighter - ran outside and reportedly began CPR. It was then that Kurek's neighbor, Dahle Amendt, said he had just settled into his recliner for a rest when he heard a woman's voice outside his house.
