UPDATE 7/11/14 10AM: Ron Haskell, multiple capital murder suspect accused of fatally shooting six members of a family in their Spring home earlier this week, collapsed during his hearing this morning. At his probable cause hearing, Haskell had to be taken out of the courtroom in a wheel chair. No word on his condition. (VIDEO BELOW)

Family members of a Spring couple and four children shot execution-style by an estranged relative say they are shocked and devastated by the tragedy, though grateful of the miracle 15-year-old Cassidy Stay survived the attack.

Prosecutors say 33-year-old Ronald Haskell posed as a delivery driver when trying to gain access into the Stay's home.

When recognized by his teenage niece, Haskell kicked in the door, tied her up and waited for the rest of his wife's family.

"He tied them, put them face down, was asking them about where his wife was.  They did not know.  He then show all seven of them execution-style in the back of the head,” prosecutors said during Haskell's initial court hearing early Thursday morning.

Police say Haskell previously has run ins with the law in Utah where he was jailed in 2008 on misdemeanors of simple assault and child neglect.

Just last week, Haskell's own mother claims he taped her to a chair, choke her and threatened to kill her for speaking with his ex-wife.

The wife filed a domestic abuse complaint against her husband after he dragged her by the hair and repeatedly punched her in the head, and five years later sought a restraining order against Haskell.

The wife filed for divorce on Valentine's Day.

Even veteran defense attorney Steven 'Rocket' Rosen is horrified by the details.

"This man obviously has mental health issues,” Rosen told KTRH News.  “Is he competent? We don't know.  Is he insane?  We don't know.”

Regardless of the nature crime, Rosen says the job of the defense is to ensure Haskell receives a fair trial.
