Tyler Mook then swam back to the boat, where Gvajardo reported he told her: 'No one disrespects me in front of my family. I will kill her.'
Andrew Mook stayed in the water with Donech until others in a passing boat picked her up and took her to safety.
Donech, flagged down a police officer at Sandsprit Park on October 4 and stated her boyfriend tried to kill her.
Donech told police she believed he was trying to drown her and would have succeeded if his brother had not intervened.
Mook was originally arrested on domestic battery charges, but those charges are now upgraded to attempted first degree murder.
The Mooks' daughter is in the custody of Shelley Mooks' mother, Debra Sikora.
Sikora told a judge in a visitation hearing that Tyler Mook used the little girl to threaten her, reports WSMV.
In regards to Tyler Mook's attempted first-degree murder charge, Sikora released this statement:
'I want the hurt to stop for those that have and are still affected by the acts of one person. Strength be to those who will stand and have their voices heard. It is by those voices that justice will come.
'By those voices, healing can begin, closure can be sought and faith in others can be restored.'
Tyler Mook is now in the Martin County jail on a $100,000 bond.
