According to the Texas Penal Code, the other types of criminal homicide are murder and capital murder. To prove a murder charge, the offender’s intent to cause the death of someone else or to inflict life-threatening injuries to that person must be established. For capital murder, the offender must have committed a murder when there was an “aggravating factor” (such as killing a peace officer or fireman). The State must be able to prove intent for a murder charge, but that isn’t the case for Texas manslaughter.
