According to interviews with cops, Jonah said he was notified by Rebecca on July 11, 2011,
while he was at the gym, that Max had an accident. He immediately rushed home, and followed the ambulance to the hospital. "He returned to his residence on July 11, 2011 in the early evening hours to take a shower and pack some clothes. He returned to the hospital, and hasn't been back to his home in Coronado,' the docs state.
Jonah was interviewed again on July 15, 2011, two days after Rebecca's death and it’s stated that in the early morning hours of July 12, 2011, he stayed at the hospital until 1:55 a.m. At that time he left the hospital and tried to get a room at the Ronald McDonald House which is across the street, but was unable to get a room because they were full, so he checked into a nearby hotel.
Jonah returned to the hospital on July 12, 2011 between 5:30 and 6:00 a.m.
Dina was at Max's bedside when Jonah returned, but left shortly thereafter to go to her home in Coronado to get some sleep.
Dina returned to Rady Children's Hospital on July 12, 2011, at 6 p.m. in the evening. Rebecca, along with Jonah's brother Adam, came to the hospital that night, and picked up Jonah and his friend Howard. After dropping Jonah's friend off at the airport, Adam, Rebecca and Jonah went out to dinner. Jonah returned to the hospital at approximately 10 p.m.
When Jonah returned to the hospital, Dina was still at Max's bedside.
Rebecca and Adam went back to Jonah's mansion after dinner. "The only people at the residence from the evening hours on July 12, 2011 to the morning hours of July 13, 2011 were Rebecca and Adam," the search warrant affirms. Jonah left the hospital around 1 a.m. on July 13, 2011, and was able to get a room at the Ronald McDonald House.
Dina stayed at the hospital for the entire night, according to the search warrant.
Jonah called Dina prior to his arrival at the hospital and notified her that Rebecca "had killed herself," the court docs state. Jonah returned to the hospital on July 13, 2011 at around 7:00 a.m., having just been notified via text message from his brother that his girlfriend was dead.
