Police in suburban Phoenix say a 22-year-old woman accused of drowning her 2-year-old twin sons says she did it because nobody loved them or her.

Mireya Alejandra Lopez was arrested Sunday at a home in Avondale (AV'-un-dayl). She's jailed on two counts of first-degree murder and one count of attempted murder, with bail set at $2 million.

Lopez is also accused of trying to drown a 3-year-old boy identified as her stepbrother.

According to a probable cause statement released Monday, Lopez said she killed her sons because nobody loved them or her, and she didn't want them to live a difficult life.

The statement also says Lopez said she takes medication for mental health conditions.

It's not immediately clear if Lopez has an attorney who could be reached for comment.
