UPDATE: Juror were unable to reach a verdict Friday and will resume deliberations on Monday.

UPDATE: The Sun's Tricia Bishop reports --The jury deliberating in the animal cruelty trial of Travers and Tremayne Johnson sent a note to the judge Friday morning suggesting that they are having trouble reaching a verdict.

The 18-year-old twins are charged with setting fire to a pit bull known as "Phoenix" in 2009, in a case that has become the centerpiece in a series of animal abuse cases. Defense attorneys say the teens were wrongly accused by Baltimore police under pressure from outraged animal welfare advocates.

Complete details of Thursday's courtroom drama can be found here. The Sun's court reporter, Tricia Bishop, wrote about Thursday's closings:

Prosecutors had spent the fifth day of trial — highlighting the evidence, while the defense team pointed to the lack of it. Prosecutors Jennifer Rallo and Janet Hankin systematically connected the dots in their circumstantial case and asked the jury to consider the testimony of their key witness, city police Sgt. Jarron Jackson, akin to that of a reporter: someone who watches and interprets information.

A defense attorneys questioned  the timing of her clients on a video and provided a list of 41 things that the police allegedly failed to do in the investigation. They did not preserve the crime scene, she said; they waited a week to assign an investigator; they didn't collect important evidence; and they didn't investigate other suspects.
