HARRIS COUNTY, Texas — Several questions remain unanswered after a 22-year-old man stabbed his mother to death early Friday morning at a home in west Houston, the Harris County Constable's Office said.

The victim, Dedré Jefferson, has been identified as a member of the Alief Independent School District school board.

The brutal attack happened shortly before 2 a.m. at the family's house in the 13600 block of Garden Grove Court inside the Westwind Townhomes.

Investigators said Blake Jefferson attacked his mother while she spoke on the phone with his grandmother. Officers said the mother, in her 40s, was acting strangely as she called the grandmother for help. The victim's screams were heard over the phone before the connection was lost, deputies said.

The grandmother called 911.

Dedré Jefferson was later found in the garage when officers arrived, she had dying from multiple stab wounds. Deputies said Blake Jefferson used several different kitchen knives during the attack.

Blake Jefferson was eventually found hiding in a bedroom closest after forcing his way into a neighbor's home, the sheriff's office said. Investigators said neighbors were able to escape the house unharmed and alerted other residents and officers he was inside.

The son was taken to the precinct for questioning, officers said.

Investigators are still searching for a motive, but it's believe an argument may have proceeded the assault.

Administrators with Alief ISD released a statement saying:

"The Alief ISD family extends its deepest condolences to Dedré Jefferson's family. We are deeply saddened by the loss of Dedré, who was a valued Alief family member and community member. Dedré was a proud Alief ISD graduate, former employee and current board member. She will be greatly missed."
