The suspected gunman of a hotel shooting Wednesday on Mississippi's Gulf Coast that left three dead was found dead hours after the attack.

The suspect, 32-year-old Jeremy Alesunder Reynolds, was involved in a two-hour standoff with police at a grocery store not far from, Biloxi, the city where the initial shooting occurred, after fleeing from a vehicle that had been carjacked, according to Adam Cooper the Gulfport Police Department's incoming chief.

The man had barricaded himself for hours inside the grocery store. Police fired teargas inside the store about 30 minutes after reaching the scene. After failing to reach a verbal deal, police entered the store to find the dead, police said.

“We're unsure of the cause of death at this point,” Cooper told reporters.

Reynolds may have assaulted another victim during the carjacking, according to police.

Biloxi Police Department Cpt. Milton Houseman confirmed that three people were killed in the hotel shooting. The shooting happened at about 9 a.m. at the Broadway Inn, according to local reports.

Coroner Brian Switzer identified to local media that the victims were 51-year-old Mohammad Moeini, who was the owner of the hotel, as well as 61-year-old Laura Lehman, an employee and resident of the hotel, and 55-year-old Chad Green, who also lived and worked at the motel.
