CATONSVILLE, Md. — A minor argument between two sisters turned deadly in Catonsville Sunday.
Brianna Kathleen Jarrells and her sister, Alyssa, just left a wedding together, before going to a friend's house on Wilkens Avenue.
At some point during the night the two siblings got into a disagreement.
It's unclear about what.
Nevertheless tensions continued to rise from there, according to a witness at the home.
Things got to a point where Brianna wanted to go home.
As the sisters walked outside to get in their car and go, the witness heard Alyssa say "oh my god."
Next thing the witness saw was Brianna leaning against the vehicle, over top Alyssa who collapsed to the ground.
The mother of three died at the hospital later that night, but not before telling police who did it.
"Where is the suspect?" one officer asked Alyssa as she laid on the driveway bleeding profusely.
"Right there," she replied, pointing to her sister Brianna.

While awaiting to be interviewed by detectives Brianna reportedly asked "do you know if my sister is ok?
According to charging documents, Brianna began blurting out statements about the incident without being questioned.
"I actually used a utility knife. I never actually tried, I pinned it up to her as a warning."
"I need to shut the f**k up." stated Brianna when realizing it might not be in her best interest to keep speaking.
Investigators ended up locating a utility knife feet away from where Alyssa was stabbed.
After declining to be interviewed, police finally told Brianna her sister died.
"Oh f**k, I thought I just nipped her," Brianna responded before breaking down into tears.
Brianna is currently being held without bail at the Baltimore County Detention Center.
A GoFundMe has been started for Alyssa's funeral costs.
