A resident of a Houston nursing home is accused of beating two of his roommates to death with the armrest of his wheelchair.

Police spokesman Victor Senties said a 56-year-old resident will be charged with capital murder in the deaths of two other men, ages 77 and 51.

Senties said it's not clear what provoked the Tuesday night attack, but that the three men did not get along. A fourth roommate was asleep.

Irma Chavez, the daughter of 77-year-old Antonio Acosta, said her father had complained about the accused attacker repeatedly, including earlier on Tuesday.

She said the nursing home told her she could move her father to a different facility.

An employee at the nursing home declined to comment Wednesday.
