Polk was last seen in the 1100 block of Indian Creek Trail on Saturday, June 8, according to detectives, driving a 2004 Black Lexus ES 330 with Texas license plate BV7-K204.
Dallas police said they communicated with the Texas Department of Public Safety every day to keep the Silver Alert for Polk going. However, since there were no updates on Polk's location, the department decided to end the Silver Alert.

Polk, a retired teacher and active church member, is revered by her loved ones as a South Oak Cliff community pillar. Her son, Philip Polk, said he knew something was wrong when his mother never showed up to their church, Exciting Singing Hills Baptist Church, on Sunday, June 9.

“It is definitely out of character for my mom to drive anywhere at night,” Polk told NBC 5 last month. “So that was an indication we thought something might not be right.”
