HOUSTON— Two young brothers were arrested Thursday in the murder of a Houston doctor who was gunned down at his Bellville ranch on Saturday.
The Texas Rangers are still looking for their cousin, who has also been charged with murder.
Dr. Jorge Mario Gonzalez was the chief of the critical care section of Methodist Hospital.

The brothers have been identified as Cristobal Galvan Cerna, 23, and Moises Galvan Cerna, 18, according to Capt. Freeman Martin with the Texas Rangers.
They are the brothers of the doctor's ranch hand, who was also shot.
The suspects were arrested in Houston and taken to Austin County where they are being held without bond.
Investigators are still looking for the brother's cousin, 18-year-old Misael Santollo.
Martin said the family had just arrived at their ranch Saturday when they were ambushed by three masked suspects waiting inside.
Dr. Gonzalez grabbed his handgun while his wife, 29-year-old Charleen Gonzalez, hid in a closet with their 18-month-old son.
The doctor exchanged gunfire with the suspects. He was struck several times and died at the scene.
Deputies said the three intruders then shot their own brother, ranch hand Noel Galvan Cerna. He was seriously wounded and remains hospitalized.
Charleen Gonzalez called 911 around noon to report a burglary in progress at the ranch in the 6400 block of South Sycamore Crossing.
Martin said they have no reason to believe the ranch hand was involved in the crime.
Investigators got their first break in the case when a Highway Patrol officer stopped a white Ford pickup that resembled the one seen leaving the ranch. He decided to let the driver go because the truck was heading toward Bellville.
Investigators followed up and discovered something that renewed their suspicion.
"We discovered that the license plates on the truck had been renewed on Monday and new plates were obtained even though the old tags had not expired," Martin said.
The truck was traced to the ranch hand's stepfather in Houston.
“It’s deeply saddening for all of us,” said Juan Mauricio Gonzalez earlier this week. “We are a tight-knit family and he was just a perfect man, a perfect father and a great physician.”
Gonzalez’s family said the doctor was a gentle man who loved his ranch in Bellville. He took his family there almost every weekend to escape the pressures of city life.
Dr. Gonzalez's funeral is scheduled for 10 a.m. Saturday at St. Vincent de Paul Catholic Church, 6800 Buffalo Speedway.
