Witness Creditability Questioned in McCowan Murder Trial

(LANSING)- Can a man who lied to police to hide his drug use be trusted in a murder case?

That's the argument Connor McCowan's attorney is making as the Okemos teen stands trial for stabbing his sister's boyfriend (Andrew Singler) to death earlier this year.

Singler's roommate was the only eyewitness to the murder, and on Thursday he admitted to keeping details from police to save his own skin. Tyler Aho admitted when he called 9-11 he lied about witnessing his roommate's murder, because he was worried about the cops finding the marijuana he was growing in his closet. Aho told dispatch that he walked into the apartment to find Singler on the floor, and was reluctant to give the address to the apartment. But truthfully, Aho was there when the stabbing happened.

"Andrew said we should go to the hospital and I agreed with that," said Aho.

"Okay, but you didn't tell the 9-11 operator about what happened because you didn't want the police to see the marijuana, correct?" said McCowan's Attorney, Chris Bergstrom.

"Correct," said Aho.

The defense says that wasn't the only thing Aho lied about since the February incident. He's also changed his story about the knife.

This is what he told police just a few hours after the incident.

"That's the thing I don't recall him pulling it out. All I saw was the motion of it," said Aho.

Now he says he saw the knife as soon as McCowan entered the apartment, and still tried to come between the two to stop the fight.

He says he didn't tell police right away because he wasn't thinking straight at the time.

"The event was obviously very traumatizing. Once my brain rebooted I could obviously think more clearly," said Aho.

Also testifying Thursday, was the officer that responded to the murder scene. He talked about McCowan's demeanor when he arrested him.

"He was very compliant, but he was deadpanned. He followed my directions as ordered, but I asked him one question and he requested an attorney. So I didn't ask him any more questions," said Officer Curtis Squires with the Meridian Twp. P.D.

Testimony continues Friday. There's no word on if Shay McCowan, Singler's girlfriend and Connor's sister, will testify.
