New details in father-son shooting

For the most part, Lazy Lane is a quiet street where conversations revolve around the next boating trip out to Galveston Bay. But today neighbors are talking about the tragedy that took place there.

According to investigators, 16-year-old Bobby Mueller and his father Robert got into an argument Sunday night. The younger Mueller then got a gun belonging to the family. First he reportedly shot his father, then shot himself.

Neighbor Slade Zapp said, "It's shocking, you know. It's just one thing after another. We just went through Hurricane Ike and it pretty much destroyed the area. Now this, it's just kind of shocking."

Neighbors weren't the only ones shocked. Bobby Mueller is a junior at Clear Lake Christian School. The school posted a tribute on its website, saying its deepest sympathies went to the Mueller family. Parents we talked could only offer prayers.

"It's very devastating to hear," said concerned parent Karen William Smith. "We've been praying since we heard that this had happened. I'm just hoping the students can bounce back from this."

Investigators with the Galveston County Sheriff's Department say they believe a disagreement over a fast food order may have played a role in starting the argument. But they don't know exactly what caused the shooting just yet.

Parents we talked to say regardless of reason, it's hard to comprehend.

Smith said, "It's very devastating, whether you know the child or the family, there's a bond, because that's your classmate."

Bobby was well-known in the school community. He played in the school band. The school has brought in counselors.

Both father and son are still listed in critical condition. The investigation continues.
