“It was clear he had no confidence in our ability to defend him,” said attorney Louis Aloise, who requested that Colon-Ortiz receive a new public defender Thursday. Aloise and Colon-Ortiz cited “irreconcilable differences” in court.

Marcotte, a 27-year-old Google executive and 2011 Boston College grad, was visiting her mother’s Princeton home from New York and went for a run the afternoon of Aug. 7, 2016. Her body was found naked and burned off Brooks Station Road, just a half mile from her mother’s home.

DNA evidence found under Marcotte’s fingernails led police to Colon-Ortiz. Police took a voluntary DNA sample from him, which matched the DNA found on Marcotte.

Colon-Ortiz was arrested in April 2016 and has pleaded not guilty to murder.

In December, the attorney representing Colon-Ortiz filed a motion stating that his client, whose native language is Spanish, doesn’t understand English and didn’t understand a police interpreter, so couldn’t voluntarily give a DNA sample. The attorney claimed that the collection of the DNA violated Colon-Ortiz’s constitutional rights.
