HOUSTON (KTRK) -- The man we've seen dressed in a FedEx shirt when he gave himself up to police Wednesday night collapsed while during reading of allegations against him in a Harris County courtroom this morning.

Ron Lee Haskell, 33, was then wheeled back out of the courtroom in a wheelchair.

Haskell faces capital murder charges in the killing of six family members. Stephen and Katie Stay were found dead in their Spring home Wednesday night. Four of their children died in the shooting. Their 15-year-old sister is the only survivor.

Haskell is accused of tying the family up before shooting them execution style. Prosecutors believe the motive was Haskell's divorce proceedings from Katie's sister. Her sister had moved from Utah to the Houston area along with the children she shared with Haskell. Records show he's been accused of domestic violence before.

The lone survivor of the shooting, Cassidy Stay, is recovering at the hospital. Precinct 4 deputy contstables say she lost a finger while trying to shield her head but likely saved her own life in the process. She also called 911 and alerted law enforcement Haskell may be headed to kill her grandparents next. He was arrested after a chase and standoff that lasted several hours wednesday night.

An official memorial page for the family has been set up on Facebook, and those who want to donate to the family can do so on
