SEGUIN -- The search for the killer of a mother and son just got a boost.

The reward has been doubled from $5,000 for information leading to the arrest of whoever murdered the two inside their home in Seguin early this month.

Today, the Chief of the Seguin Police Department held a news conference urging the public to come forward if they know anything.

"It's kind of disturbing and scary at the same time to know that these people are still out," said some of the victims’ neighbors.

Ten days have passed and still no suspect or suspects connected to the murder of 29-year-old Jeremy Sauceda and his mother Belinda.

"The mother is legally blind,” said Chief Kevin Kelso. “There is no reason for this to happen."

Kelso said on Nov. 6 officers got called to shots being fired.

"They heard five or six shots," he said.

Officers were nearby and when they arrived at the duplex, they found Jeremy and Belinda shot dead.

Chief Kelso said it did not appear to be a random home invasion, but he said someone in the house was targeted. However, the motive is not clear. No one can remember a double homicide ever in his city.

"I've been here for nine years almost and I haven't seen one," he said.

The shattered glass next door was from the neighbor’s house.

"They were victims as well there were shots fired at the neighbors as well nobody was hurt," said Chief Kelso.

A neighbor said she wants the truth to come out soon.

"Some nights it’s still hard to stay home."

The chief said there was one other person inside the home when the Saucedas were shot and would only say it was a family member.

A background check on Jeremy shows he had been convicted of multiple drug-related felonies and misdemeanors.
