"There were reports on her being run over or being shot or both, but that will not be confirmed until the autopsy is complete", Baltimore County Police Department spokesman Matt Kuhn said in a phone interview.
"Our prayers go out to this courageous officer's family, @BACOPoliceFire, and the Baltimore County community", a portion of Gov. Hogan's tweet said.
Speaking on radio station 105.7 The Fan, Caprio's husband Tim Caprio said, "I'm just still grieving".
"She suffered significant injuries", Vinson said. Authorities say Harris drove over Caprio in a stolen jeep. The boy is being charged as an adult, according to court documents, and is being held without bail. The Baltimore County Police and Fire Twitter account shared information about the investigation. According to the documents, the caller told the dispatcher that the officer had confronted the driver of the Jeep and was "on the ground".
Caprio was rushed to the hospital where she was pronounced dead.
Harris also told the detective that he "drove at the officer", the statement said.
Authorities in Baltimore County have identified the police officer they say was killed on Monday.
A statement of probable cause issued today identified Dawnta Anthony Harris as the suspect in the killing of Officer Amy Caprio. Genius at first declined to give a statement but later objected to being charged with murder, saying he was in the house when the killing occurred, another statement said.
They are suspects in a string of burglaries in the area, according to police. The department did not say whether the three played any role in the officer's death and have not released their identities.
She was responding to a call about a suspicious vehicle when she found Harris at the wheel of the auto.
Someone saw the Jeep Wrangler drive directly at Caprio, striking her and then fleeing the area, according to the documents. Shawn Vinson said investigators have recovered the suspects' abandoned Jeep, but police declined to confirm whether it was used to injure the officer. The Associated Press does not ordinarily identify underage suspects unless they face adult charges.
Court records don't list an attorney for Harris, and attempts to reach people believed to be his family members were not immediately successful.
Harris is scheduled to appear before a judge at a Towson, Maryland, courthouse at 1 p.m. Tuesday.
In December, she won the "Officer of the Month" award for the Parkville precinct.
"Our prayers go out to this courageous officer's family, @BACOPoliceFire, and the Baltimore County community", Maryland Gov. Larry Hogan said in a tweet.
Police said detectives verified that the suspects were involved in burglaries in the area.
Scott Shellenberger, the state's attorney for Baltimore County, told The Associated Press that the 16-year-old has been charged as an adult.
"The next thing he heard was a pop, and he saw the Jeep take off and run right over her", said Kurek. The auto left skid marks, he said, and officer was on the ground bleeding.
One of the Kureks' other sons - a volunteer firefighter - ran outside and reportedly began CPR.
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.
"I heard, 'Get out of the car!' 'Get out of the car!' Get out of the car!' at least three times, and then a pop", Amendt said. She turned around, exited her patrol vehicle and ordered the driver to get out of the Jeep.
Vinson said the family of the officer, who would have been a four-year veteran in July, has been notified.
