“Evidence, statements and a robust police investigation led us there,” Olmos Park police said in a statement posted on social media by Simpson’s brother-in-law, Barton Simpson.

Police said they are currently in a “search phase” taking place at a landfill southeast of Olmos Park.

The 51-year-old mother went missing the night of Oct. 6 near Trinity University in San Antonio, police said.

In one post On social media, San Antonio Police Chief Bill McManus said Wednesday morning that the Olmos Park police chief had asked for help in the search, prompting McManus to send 25 cadets to assist. Olmos Park is located north of San Antonio.

“We take comfort in the fact that they may be close to finding out what happened to Suzanne,” Barton Simpson wrote.

Police arrested Simpson’s husband, 53-year-old Brad Chandler Simpson, days later on two misdemeanor counts of assault on a family member and unlawful restraint. He remains in jail with bail set at $2 million on both charges, according to Bexar County online records.

A neighbor said he heard the couple arguing outside his window and then heard screaming.
