Defense attorneys for the man accused of killing a woman jogging in New York City last summer suggested there was doubt about the admissibility of prosecutors' evidence as well their client's alleged confession. Lawyers for Chanel Lewis, who was arrested in February for allegedly murdering Karina Vetrano in the Howard Beach neighborhood of Queens in August, hinted on Monday that their client could be exonerated of the violent charges.

"We remain concerned with how the NYPD collected the DNA evidence, the infallibility of DNA evidence in general, and the voluntariness of our client's statements," the Attorney-in-Charge of the Criminal Practice at The Legal Aid Society, Tina Luongo, told the New York Daily News on Monday. "As such, the reliability of the prosecution's evidence will be fully litigated in this matter. There are way more questions than answers here."

According to the New York Police Department, evidence against Lewis seemed to damning, including his DNA being found under Vetrano's fingernails and a confession admitting to committing the killing.

Lewis' defense team seemed to be making a concerted effort to get spread their message in the media, as the comments Monday came days after the accused killer's mother said her son was "innocent" in an exclusive interview in the Daily News.

"God didn’t give me a murderer," Veta Lewis said Friday. "We are all God-fearing people. I know my son is innocent and never would have done something like this."

Meanwhile, Vetrano's family was moving on after finding a semblance of closure with the arrest of Lewis, 20. The 30-year-old jogger had planned to participate in a marathon in Cuba last November before she was killed in early August. As a way to carry out Vetrano's plans, her father said that he and his family and friends visited Havana last month, Newsday reported.

"That was on Karina’s bucket list," Philip Vetrano said. "I intend to fulfill all those things on her list."
