Missing Louisiana Tech mascot actually dead

RUSTON (AP) — Louisiana Tech University's mascot, Tech XX, has died.

The 4-year-old English bulldog and face of

the university was reported missing Sunday from the Ruston animal clinic

where

he'd been staying. Authorities initially said the animal had been

let out for a bathroom break and when a worker went to bring

him back inside, Tech XX was nowhere to be found.

On Wednesday, Dr. Patrick Sexton, the clinic's owner, reported the dog had died of heat stroke on Sunday.

"Regretfully, I learned this morning that

through negligence of an employee, Tech XX was left outside too long on

Sunday evening

and passed away from a heat stroke," Sexton said in a statement

released by the university. "That employee unfortunately chose

to handle it the wrong way and attempted to cover it up. Due to

this negligence, the employee is no longer employed by Sexton

Animal Health Center."

Tech XX was named mascot in 2008, replacing Tech XIX, who retired due to health concerns.

Sexton said he, his family and staff were "extremely upset at this tragic turn of events."

"Tech XX was a member of our immediate family and a daily part of our lives for the past four years. We are devastated over

the circumstances of his passing and there will be a large void in our hearts for some time to come," he said.

The university, in a statement, said it was

saddened to learn of Tech XX's death. "He will be remembered for being a

fan favorite

and a symbol of the spirit of Louisiana Tech."
