The investigation continues into what exactly happened in the moments leading up to Wednesday’s officer-involved shooting at the Royal Mall Apartments in Niles that killed Matthew Burroughs.

“Everything that we have relative to the case, we have handed over to BCI and they are in the midst of their independent investigation,” said Niles Police Capt. John Marshall.

A Bureau of Criminal Investigation truck was parked outside of a garage at the Niles Police Department on Friday afternoon.

Inside, investigators with the Ohio Attorney General’s Office conducted a search warrant on the vehicle Burroughs was driving. Agents have finished collecting evidence from the vehicle.

A BCI spokesperson said they did not find a gun inside the car but part of their investigation will be to determine whether or not the vehicle was used as a weapon.

They’ll continue to collect and analyze evidence in the case while awaiting autopsy and toxicology results.

A final report could take months.

“It definitely could. A lot of it is definitely dependent on interaction with the coroner’s office and other factors of the investigation that could take some time,” Marshall said.

BCI’s findings will be turned over to the prosecutor’s office once the investigation is complete.
