Prior to his death, the Teen Mom star was slammed for returning to Indiana as her father remained in a coma in Florida. However, according to Portwood, she had good reason for going back to her home state.

"Just to clear the record I was in Florida the morning after I found out my dad was in ICU and by his side until I left this morning," Portwood wrote on Monday, one day prior to her father's passing.

On Thursday, Radar Online confirmed Shawn Portwood's death, revealing the Teen Mom star's dad underwent liver surgery on Dec. 11 and was later placed in a medically-induced coma. At the time of his passing, he was awaiting a liver transplant.

Following the loss of her father, Portwood released a statement to fans.

"I just want to say thank you to everyone for all your kind words," she told fans on Twitter. "This is a heartbreaking time for my family your prayers help..love always."

Last week, according to Radar, Portwood and her new boyfriend, Matt Baier, 43, drove from Indiana to her father’s Florida hospital. Days later, after coming down with a case of strep throat, she returned to Indiana.

Portwood is now said to be on her way back to Florida.
