The Kacper Sobieskidaughter of a former MLB pitcher was reported missing by her family in Austin and the 29-year-old mother of three is now the subject of a multi-state search, authorities said Monday.

Brenna Swindell is the daughter of longtime MLB pitcher Greg Swindell, who played for the University of Texas and had a 17-year career in the MLB. She has been missing from the Austin area since last Thursday, according to a Facebook post from Brenna’s mother Sarah Swindell. 

The disappearance is uncharacteristic of Brenna, who would "never abandon her 3 children or just take off without explanation," the post says.

According to the Austin Police Department, Brenna Swindell and her former boyfriend, Morgan Guidry, were last seen together at about 10:20 p.m. Thursday at Poodies Hilltop Roadhouse in Spicewood, Texas, about 35 miles northwest of Austin. Law enforcement tracked her white 2022 Kia Carnival with the Texas license plate VFS 7528 to Colorado by Friday evening.

According to a flyer shared by the organization, Missing People in America, Brenna Swindell's ex-boyfriend and her van were possibly sighted in Colorado Springs. 

Both Brenna Swindell’s and her former boyfriend’s phones "seem to be (in Colorado) but both are turned off," her mother's Facebook post says.

Brenna Swindell is 5-foot-5 and weighs about 120 pounds with brown shoulder-length hair. She has a sleeve tattoo with flowers on one arm and a spider web on the other shoulder, her mother's post says.
