A day after emotional verdict, more witnesses will testify in the sentencing phase of ex-cop Amber Guyger

(CNN) More emotional testimony is expected Wednesday in the sentencing phase of the trial for former Dallas police officer Amber Guyger, who was convicted of murder in the shooting death of Botham Jean.  Allison Jean, his mother, took the stand first when the sentencing hearing began Tuesday, hours after raising her hands in jubilation when the guilty finding was announced.  Jean and her daughter were largely composed as they addressed the jury, describing how losing Botham had upended their lives.  “My life has not been the same,” Allison Jean told the jury that will sentence Guyger. “It’s just been like a roller coaster.”
