Crime Young Mom Allegedly Stabbed to Death by Drifter While Working Out at Her Luxury Apartment Gym Carina Rodriguez was killed while working out, allegedly by a homeless drifter, police say By Steve Helling Published on October 18, 2017 11:15 AM Share Tweet Pin Email Photo: Facebook Carina Rodriguez had recently moved from Texas to Indiana to begin a new life with her young son and to get a college degree in the medical field. But she never got the chance. On Friday, according to Indianapolis police, the 23-year-old was stabbed to death in the gym of her luxury apartment complex, allegedly by a homeless man whom she had let into the locked facility. Investigators don’t believe Rodriguez previously knew her assailant. Cody Weir, a 25-year-old drifter later found in a parking lot, was arrested Friday night in connection with Rodriguez’s death. Police say surveillance video shows him entering her apartment complex before she was killed. At a news conference, Indianapolis Metro Police Department Chief Bryan Roach said authorities believe they found the right man — and, as proof, he pointed to the suspect’s demeanor during his arrest. “You could tell he knew why we were there,” Roach told reporters, according to local TV station WXIN. “[He was] tearful at one point, knew it was happening, knew it was coming, I think.” Weir is being held without bond and has pleaded not guilty to a charge of murder. In court on Tuesday, he told the judge that he does not have an attorney. If his family does not hire one for him, he will be assigned a public defender. • Want to keep up with the latest crime coverage?

Police released parts of the video on Friday and, according to Chief Roach, several people called in to report Weir as a possible suspect. The arrest report states that Weir allegedly told police he didn’t remember anything. But he said that he used a knife for work and recalled the victim letting him into the gym, the report claims. “I think I knocked on [the door], and she let me in, and I told her ‘thank you,’ ” he allegedly told investigators, the police documents show. “I had a knife in my hand. I remember hitting her and then I ran.” A search of Weir’s vehicle uncovered a knife with “possible blood on the handle and blade,” according to court documents. Police also found a hooded jacket, work boots and jeans that had “possible blood” on them. The items have been sent to a lab for testing.
