A relative of a woman convicted of helping a New Kensington police officer’s killer escape seven years ago is wanted for threatening to shoot a woman “like we shot up Brian Shaw,” police allege in court paperwork.

An arrest warrant was issued for Mayona Dania Harrington, 19, of Arnold. New Kensington police charged her Friday with burglary, terroristic threats and criminal mischief.

Lisa Harrington was sentenced in September 2020 to serve three to seven years in prison for helping her cousin, Rahmael Holt, flee New Kensington after he shot and killed Shaw after a traffic stop Nov. 17, 2017.

Holt was convicted in November 2019 of first-degree murder and sentenced to death. The state Supreme Court upheld his death sentence in April 2022.

About 7:30 p.m. Sunday, Jan. 5, an officer went to the 1300 block of Leishman Avenue after a report of a group of people, possibly armed, trying to get into a home, a criminal complaint states. The people fled toward Constitution Boulevard before the officer arrived.

The woman who called told police Mayona Harrington came to her home with several others with the intention of “jumping” her, the complaint states. After the woman’s friend closed the front door and locked it, the woman said Harrington tried to break it down.

The officer reported in court records the frame of the door was caved in, the doorknob was knocked off, and there was mud and wet snow on the door.

The woman said Harrington made threats to “shoot you (her) up like we (she) shot up Brian Shaw,” the complaint states.

Others in the house identified two of the vehicles fleeing the scene as a white minivan and a silver sedan.

In the 1700 block of Constitution Boulevard, officers reported seeing a group of people walking from near the white van owned by Lisa Harrington and going inside a residence. A man answered the door and pretended nobody else was in the house and that he did not know anything, according to the complaint.

Police said Mayona Harrington and Lisa Harrington arrived at their station later. According to the complaint, Mayona Harrington admitted to being at the Leishman Avenue house, arriving in a silver sedan, but said she did not know who tried to break down the door.

After at first claiming she arrived at the house by herself, Mayona Harrington admitted to being there with others, but would not tell police who they were, the complaint states.

A Facebook Live video from the woman inside the home shows a woman matching Mayona Harrington’s description walking up to the front door before it is shut and locked, the complaint states. Knocking on the door is heard followed by someone trying to break down the door while the woman inside tries to hold it shut.

Security footage from the home shows Mayona Harrington and a large group of people arriving in multiple cars and yelling, “You was talking all that (expletive) on Facebook,” and “Come outside!” the complaint states.

There are then multiple people screaming, and what was said can’t be made out, police said.

They are then heard trying to break down the door before getting back in their cars and leaving, the complaint states.
