PLAQUEMINE - A convicted murderer who escaped custody as he was being brought to court for sentencing last week was sentenced to life Wednesday morning. 

Tyler Jackson was back in court Wednesday for his sentencing in a murder case and to be arraigned on new charges tied to his escape.  He was given a life sentence, which is mandatory for a second-degree murder conviction. 

Iberville Sheriff Brett Stassi told WBRZ that Jackson escaped last week as he was being let out of a transport van near the courthouse in Plaquemine. A school near the courthouse and the parish Council on Aging office were locked down as a result.

The sheriff's office said Jackson was captured within the hour. He was found hiding in a garbage can. 

Sheriff Brett Stassi said an investigation is underway to determine how he got away in the first place.

"I make no excuses for what happened," Stassi said. "I am responsible, bottom line. Mistakes were made and it may have been human error what we thought was a secure area, but this is on me and I want to thank everyone who came out to help. You hate to lock down a school, the council on aging and the courthouse, but it had to be done. He was back in custody within 50 minutes."

Jackson was convicted of second-degree murder just weeks ago for a 2018 shooting that happened at a party in White Castle.

Last month, several people were arrested after they allegedly filmed witness testimony during Jackson's trial and posted it to social media in an attempt to intimidate those witnesses.
