ALBANY, N.Y. -- The jury in the Jah-Lah Vanderhorst murder trial will return Tuesday morning, after failing to reach a verdict in the case Monday night.

The jury deliberated for about four hours Monday before calling it a night. However, just before the judge was about to dismiss them after 10:00 pm, they sent out a note, requesting definitions of certain terms and readbacks of a number of testimonies, including Vanderhorst's.

The 17-year-old is accused of killing Tyler Rhodes, 17, in Albany's Hoffman Park back in April of 2011. The stabbing was caught on cell phone video and on Monday, Vanderhorst admitted that he killed Rhodes, but claimed he did so in self defense, and there was an ongoing conflict between the two teens.

The prosecution has relied heavily on the video evidence, in which they said, Rhodes was not the aggressor, but Vanderhorst was.

“He has to have believed that deadly physical force was about to be used against him and in addition to that, he couldn't get away. There was no other choice. So that's really what this case boils down to,” said Chief Assistant District Attorney Dave Rossi.

Defense attorney Matthew Alpern refused to give comment following the day's proceedings.

If convicted of second degree murder, Vanderhorst could face 25 years to life in prison.

However, if the jury does not find Vanderhorst guilty of second degree murder, they will then decide on the charge of first degree manslaughter. If he is found innocent of that, they will deliberate on a second degree manslaughter charge.

One of the items the jury requested in their last note Monday night was the definition of "intent to cause serious injury;" the definition of manslaughter in the first degree.

The jury will return at 9:30 am, but deliberations will be short as the requested information Court is expected to adjourn at around 11:00 am or 11:30 am.

Vanderhorst's co-defendant, Dhoruba Shuaib, was convicted of manslaughter in a trial back in February. He was sentenced to 21 years in prison.
