The aunt and uncle of San Francisco 49ers tight end Delanie Walker were killed in a crash caused by an alleged drunken driver early Monday morning in Louisiana after the Super Bowl in New Orleans.

Walker posted on Twitter Wednesday morning that his relatives Alice and Bryan Young were killed in the crash just hours after the 49ers' 34-31 loss to the Baltimore Ravens.

“I'm going to miss y'all but I know they are in a better place,” he wrote, while also including two pictures he recently took with his aunt and uncle.

The NFL's website said the deaths were linked to a crash in St. Charles Parish, La., shortly after 5:30 a.m. Monday.

According to Louisiana State Police officials, the crash was caused by Nechole Thomas, 26, of Houston, who was allegedly intoxicated and rear-ended a 2012 Nissan Altima stopped on the side of the road.

Both vehicles caught fire and the driver and passenger inside the Altima were killed. The St. Charles Parish coroner's office has not officially confirmed Alice and Bryan Young as the victims.

Thomas survived with minor injuries but was arrested on suspicion of two counts of vehicular homicide, DWI and reckless operation of a motor vehicle, police said.

Walker received an outpouring of support on social media on Wednesday, including from 49ers owner Jed York, who wrote on Twitter, “We are praying for you and your family.”
