How can I help my friend get over the death of her nephew?

Hey this is a question about my friend and her family. A few weeks ago my friend Emily went shopping with her sister Morgan. Morgan and her husband Juan have 3 kids, Selena age 33 months, Bridget age 33 months, and Andrew age 9 months. So a few weeks ago when they went shopping, Morgan had the babysitter come over to watch the kids. They have known her since the twins were born and trust her. When the twins were sleeping, Andrew was crawling around because he refused to sleep. The babysitter was in the den watching tv. During lunch she had used scissors to cut open something and put them on the counter. They had fallen on the floor but she didn't know. So when Andrew was crawling around he found the scissors. So about 10 minutes later Morgan and Emily arrived home. When Emily walked in the house Morgan heard her scream. There was Andrew laying on the floor in a pool of blood dead. He had cut his mouth and throat. It's been a few weeks and the whole family is still devastated especially Emily and Morgan. Emily is 18 and in college and Morgan is 26 and a 2nd grade teacher. They both take a shower every night and just cry for about 2 hours. The only time they leave the house is when they go to church. Emily hasn't been to school and Morgan hasn't been to work. Is there anything I can do to help them get over it? PS if you don't believe me don't answer.
