DALLAS -- A former state wrestling champion from Sarasota was arrested after police say he choked his mother to death over the weekend.
Gonzalo Roberto Lopez, 25, who once wrestled for Sarasota High, told police: "I choked my mom," according to an arrest warrant affidavit.
Police found 51-year-old Isabel Kristina Lopez dead in her upstairs bedroom.
The pair were well known in the local high school wrestling community, where Isabel Kristina Lopez ran the concession stand to raise money for the team. Her son won the state wrestling championship in the 145-pound division in 2005.
Isabel Kristina Lopez's hands were tied together and a television cable wire was wrapped around her neck, according to the arrest warrant affidavit.
Lopez is being held at Dallas County jail on $750,000 bond.
A friend of Isabel Lopez contacted police after he received a cell phone call from her, heard a disturbance and noticed her phone line went dead, according to the arrest warrant affidavit. The friend, who lives in Oklahoma, told police Lopez's son was known to be violent.
When police arrived, Gonzalo Lopez went inside the apartment with them and said: "I think she's dead" or "I killed her," according to the arrest warrant affidavit.
In a police interview, he said he got into an argument with his mother, placed her into a wrestling hold and choked her to death, according to the arrest warrant affidavit. When she stopped breathing, he said he bound her hands and neck in case she woke up.
