TRAVERSE CITY -- The jury continues to hear emotional testimony on the second day of Robert Jensen Schwander's murder trial.

Traverse City Police Sgt. Joe McCarthy took the stand and told jurors that Schwander's dad, who is a Grand Traverse County Deputy,  brought his son in for another round of questioning after investigators noted some discrepancies in his first interview with police.

Sgt. McCarthy said he's known the Schwander family for 20-years. Schwander began to cry as Sgt. McCarthy played a recording of the teen confessing to kill Carly Lewis. The detective had secretly recorded the conversations on a walk with Schwander.

Sgt. McCarthy held back tears as he told the jurors he couldn't give a positive identification of Carly Lewis at the morgue because of her injuries and the decomposition of her body.

Schwander led police to a sand pile near the public works building were he told them he buried the body.

This afternoon Dr. Stephen Cohle, a Forensic Pathologist from Grand Rapids testified that Carly was stabbed before she died and that he found little evidence that she was strangled.

In opening arguments Wednesday the defense told jurrors they had evidence that showed the probes used to find Carly's body caused the stab wounds and that Schwander had strangled Carly during an argument.

The testimony continues Thursday afternoon.  7&4's Lauren Amstutz is in the courtroom and will bring us the latest details on the trial coming up on 7&4 News at 5, 6 and 11.
