Four people were dead and at least one was hurt in Maryland, Sunday morning, after a shooting and fire incidents.

Police said that the suspect of the shooting was shot by the police and was among the deads.

Authorities said it is not yet clear what ignited the incident that happened in a residential street in suburban Baltimore.

The fire which followed a shooting destroyed at least two residents of the streets. 

Baltimore County Police spokeswoman Joy Stewart said at a news conference that officers responded to reports of both fire and active shooter in the neighborhood in Woodlawn, west of Baltimore, around 6:40 a.m. She also said the armed suspected at the scene was shot dead by the police.

“We have this fire that happened. We also have this suspect who was armed. How they’re all related, it’s really too early to tell at this point,” Stewart said.

Police said the investigation that was opened involved several law enforcement agencies at the local, state, and federal level.
