Mom and brother of teen killed after birthday arrested in unrelated robbery

HOUSTON, Texas (KTRK) -- The mother and older brother of a 14-year-old gunned down the day after his birthday have been arrested and sources tell Eyewitness News their arrests led to a confession to the killing.

Ellen Breaux and her 17-year-old son, Messiah Breaux, were taken to jail Wednesday night, charged with aggravated robbery with a deadly weapon.

"Mrs. Breaux, were you involved in some aggravated robberies," asked Eyewitness News Reporter Jessica Willey.

"(Expletive) no. That is (expletive) crazy," replied Breaux as she and her son, handcuffed, were walked to a patrol car.

Eyewitness News has learned the charge stems from a carjacking that happened last month, weeks before Breaux's 14-year-old son, O'Cyrus Breaux, was killed. It's unrelated to his death.

However, during questioning, Messiah confessed to killing his brother, according to sources close to the investigation.

"Please don't (expletive) ask my son that," said Ellen Breaux.

On Monday, Breaux's mother was in tears, crying so hard she could barely get the words out. She said he was good son and didn't know the details of what happened in the shooting.

Breaux was hanging out in a driveway around 2 a.m. off Goodson Drive in the Greenspoint area when he was fatally shot.

The honor roll student had just celebrated his birthday with family in north Houston.

Investigators believe the mother and son are linked to more aggravated robberies and that she is the leader of a northside robbery crew.

"(Expletive) no," she scoffed. "Come on, man."

Neither has been charged in the 14-year-old's case. That investigation continues.

"The scenario hasn't changed," said Pastor E.A. Deckard, of Greenhouse International Church. "A 14-year-old honor student, respectable student, model citizen, is a victim of a senseless crime."
