A Rockwall mother of three children died Saturday. Police believe Jessica Aguilar's ex-boyfriend, former Hunt County Constable Anthony DeWayne Lewis killed her before leading police on a pursuit and gunfight.
NBC DFW talked with the Aguilar's son, Jaime Puente. He said Lewis approached his mother at his sister's basketball game hours before she died on Saturday night.
"He wasn't being violent," Puente said. "My mom was just trying to be civil... She let him stay there."
According to Puente, Aguilar and Lewis met about five years ago at work. She was an apartment complex manager and he worked security. They had recently split.
"I just had that feeling that there something wrong," Puente said. "He got mad way too easy."
He adds that Lewis was upset at the fact that Aguilar had started dating again.
Lewis served as constable in Commerce, until he was defeated in the recent Republican Primary. He left office January 1. His law enforcement experience was a factor in the officers' response.
“It certainly made us consider our tactics given that he knows how we operate,” Rockwall police Sgt. Aaron McGrew, with Rockwall Police said.
Once the chase ended in Greenville, a standoff ensued.
"The suspect produced a handgun and pointed it to the direction of the officers," Sgt. McGrew said. "Officers from several agencies opened fire at that point."
Aguilar’s companion, Francisco Delacruz, was taken to Baylor Hospital and is expected to survive.
Lewis is at Parkland Hospital in Dallas. His condition was upgraded to serious on Monday morning. He is charged with one count of murder on one million dollars bond and one count of attempted murder with a $500,000 bond.
