Dyersburg Mayor John Holden told WREG he can’t confirm that the incident happened at a birthday party.

However, he did confirm that there was an incident earlier in the day at the same residence. Authorities think the two are related and this act of violence was not random.

Several others were taken to the hospital in Dyersburg where it subsequently was put on lockdown Thursday evening.

Hospital policy dictates when multiple victims are brought in from the same crime scene, the emergency room goes into lockdown for everyone’s safety.
