VIDEO: Man Wanted for Killing Delaware Trooper Fatally Shot by Police After 20-Hour Standoff

Delaware State Police have identified the man who shot and killed a trooper on Wednesday, and was then killed himself by police gunfire on Thursday morning after a lengthy standoff.

He is identified as 26-year-old Burgon Sealy Jr. of Middletown, Delaware. He was shot after a nearly day-long standoff with police at his home.

Cpl. Stephen Ballard, 32, was shot in the parking lot of a Wawa in Bear, Del. around 12 p.m. Wednesday.

Sealy fled from the scene of the shooting then called family members, police say, and said he shot a trooper at the Wawa. His family immediately called police.

With that information, police were able to track Sealy down to his home in Middletown, 6ABC reports.

Police arrived, secured a perimeter, and attempted to make contact with Sealy. He then fired multiple rounds at the officers from inside the home, commencing a barricaded suspect incident.

When Sealy stopped communicating with officers at about 8:22 p.m., the ordnance unit used an explosive breaching charge on the front door.

Still, Sealy failed to respond and the standoff stretched into the overnight hours. At around 4 a.m. Thursday, officers reported hearing gunshots from inside the home. Again, police say they tried to make contact, but got no response.

Then, at 9:17 a.m., Sealy emerged from the home, engaged police, and was shot by officers. Rescuers on the scene began efforts to save his life, but he was pronounced dead at 9:22 a.m.
