Dallas convenience store murder suspects Don Williams (L) and Lamarcus Mathis (R).

DALLAS (CBSDFW.COM) – Deputy Chief Craig Miller with the Dallas Police Department’s Crimes Against Persons unit released new information Tuesday in the murder case of storeowner Jin Ha.

Investigators have released the names and pictures of two remaining suspects — 17-year-old Don Williams and 19-year-old Lamarcus Mathis.

Newly released surveillance video also shows the suspects approach Jin Ha and her husband as they closed the Quick Check Grocery store in the 3000 block of E. Illinois Avenue, in Oak Cliff.

According to police, Williams approached the couple with two guns drawn. Surveillance video clearly shows one of the suspects firing at Jin Ha, multiple times. Police say Williams is the shooter. Suspect Mathis is also seen in the video.

Police say the teenagers were attempting to rob the couple and specifically wanted a box Jin Ha was holding. The suspects believed the box had money in it, but Deputy Chief Miller said it didn’t contain a single dime. “We now know she only had her half-eaten lunch, with some onions, in that box,” said Miller. “That’s all they got.”

The reward for information leading to an arrest and conviction in the case has been raised from $10,000 to $15,000.

One suspect, Robert C. Roberson, has been arrested and charged with capital murder in the case. The 24-year-old is accused of driving the vehicle used during the crime.

Millers said, “The act is blatant, senseless and cowardly.”

The Dallas Police Department is working with U.S. Marshals to find Williams and Mathis and say they believe the two are in North Texas.

“These people need to come off the streets of Dallas,” stressed Miller. “We need to arrest them.”

Anyone with information about the suspects, or the case, is asked to contact the Dallas Police Departments Homicide Unit at (214) 671-3661 or Crime Stoppers at (214) 373-8477.
