POMONA – An eyewitness Monday appeared to bolster the case against three people suspected in the kidnapping, robbery and killing of a Cal Poly Pomona student in 2001. Chanson Tyrone, 29, testified at a preliminary hearing at Pomona Superior Court that he was with a friend, Henry Singer, and James Winslow Dixon and his wife, Markeisha, on the night of Christina Burmeister’s disappearance. Tyrone described how a possible drug deal turned into a brutal slaying, revealing accounts of the evening’s events that closely resemble physical evidence police have already gathered in the case. Tyrone’s identity was kept under wraps until Monday, and he has been relocated with the assistance of the Los Angeles County Sheriff’s Department. Markeisha Dixon asked him if he wanted to make some “cheese” by “flipping” drugs, Tyrone said. The witness was known in the area as a drug dealer. The four drove to Pomona when things went awry, Tyrone said. He noticed a gun on James Dixon’s lap. Some time later, James encountered a young blond woman and entered a truck with her. The parties then went to a bank where Markeisha Dixon allegedly used Burmeister’s card to access a Montclair ATM. Markeisha Dixon complained about the difficulties of driving the truck, so she and Singer switched vehicles, Tyrone said. Both cars then headed to some secluded mountains. Singer exited the truck, and Tyrone said he saw the blond woman appear to grab her throat as if she was gasping for air. Christina Burmeister’s parents along with other family members and friends sat in on the emotional testimony. “I’m glad we are further along the process,” said Rosi Burmeister, Christina’s mother. “I do believe they will be convicted. All we have asked for is justice for our daughter. No one deserves to die this way.” Singer and Markeisha Dixon are scheduled for arraignment on April 24.

She was found with her throat slit in her truck on a turnout off Highway 39 above Azusa the next morning. James Winslow Dixon, 33, was ordered to stand trial last year for her murder after investigators linked him to DNA left on a cigar found in Burmeister’s truck. Prosecutors will seek the death penalty. On Monday, Judge Daniel J. Buckley ordered Markeisha Dixon, 24, to stand trial for murder with the special circumstances of kidnapping and robbery. Singer, 27, was also ordered to stand trial for murder with a special circumstance of robbery. Deputy District Attorney John Monaghan said he intends to add a kidnapping charge against Singer, but he would not say if he would seek the death penalty. Tyrone described how he and Singer were approached by Markeisha Dixon, who was driving a car as the two were walking to a liquor store in San Bernardino. He said he knew the Dixons from an apartment complex where they all lived. James Dixon was in the passenger seat, Tyrone said.
