While authorities gave an update on Wednesday’s mass shooting on Thursday morning, there are still some things we don’t know. They include:

• The identities of the suspects. Authorities said three people are in custody, two of whom are juveniles.

• What charges, if any, the people who have been detained may face. Kansas City Police Chief Stacey Graves told reporters on Thursday morning that charges hadn’t been filed against anyone. “This is still under investigation. We do have 24 hours until we either have to file charges or release them,” Graves said.

• The exact motive. Officials said the shooting was not linked to terrorism or homegrown extremism and that the gunfire appeared to be the result between a dispute between several people.

• Whether Lisa Lopez-Galvan, who was killed in the shooting, knew the suspects. Galvan was a local DJ who co-hosted a radio show on KKFI-FM and performed at weddings and other private events in the area.
