Can a defendant challenge the amount of restitution ordered by a judge in a personal injury case where the recipient's injuries were caused by suicide?

subject to challenge by defendant regardless of who the recipient was. Defendant did not object in the trial court to the amount of restitution ordered. His sole objection was that restitution for these expenses was improper because the victim's injuries resulted from a suicidal act. Defendant has waived a claim of error as to the amount of restitution by failing to object on that ground in the trial court. [Citation.]" (Ibid.; see also People v. Gonzalez (2003) 31 Cal.4th 745, 755 [defendants objected in the trial court that they should not pay restitution for items taken from the victim's house when they were not convicted of stealing those items, and therefore "on appeal they may challenge their sentences on that ground"].)
